High-functioning anxiety: in control on the outside, an alarm ringing inside

“You really are amazing. How do you manage it all?”

She heard this at an end-of-year party, when a colleague listed everything she had pulled off in a single year: a project nobody else wanted to take on, a house move, her mother’s operation, getting her child into music school. She smiled and said something modest. Nobody knew that she had lain awake until three that night, replaying for the third time what she had said wrong in a meeting. Nobody knew that her jaw had been clenched for months, that she checked her email before she even opened her eyes, and that a free weekend did not feel restful but restless, as if she were missing something.

More and more people call what I am describing high-functioning anxiety. The term has spread online because so many people recognise themselves in it: on the outside you have everything under control, on the inside an alarm is constantly ringing. In this post I will try to explain what lies behind the term, why the people around you almost never notice, and why this kind of coping comes at a price.

First, let’s be clear: this is not a diagnosis

High-functioning anxiety is not an official diagnosis. You will not find it in the American diagnostic manual DSM-5 or in the International Classification of Diseases, ICD-11. It is a descriptive term that has caught on in conversation, on social media and in popular articles. This is important to say at the start, for two reasons.

The first reason: the term does not tell you whether there is a disorder. Someone who recognises themselves in the description may have a perfectly ordinary, perhaps slightly raised level of worry that they manage well. Someone else may have generalised anxiety disorder, panic attacks or depression in the background, simply hidden behind a work schedule. No online questionnaire can make that distinction; a conversation with a professional can.

The second reason: anxiety itself is not rare. A large American study, in which Ronald Kessler and colleagues published data on more than nine thousand adults in 2005, found that almost one adult in three (28.8%) meets the criteria for an anxiety disorder at some point in their life. Among them are many people who go to work, raise children and would never be described as “anxious”. So the term high-functioning anxiety does not describe a special group of people, but a particular shape anxiety can take: one that turns itself into reliability.

What it looks like from the inside

When people describe how they experience it, the stories repeat themselves surprisingly often. Not everything applies to everyone, but the common thread is clear:

• A mind that runs ahead of the day. Before anything has happened, you already have five scenarios ready for what could go wrong — and a plan for each.
• Checking. You read an email three times before sending it. At night you go back to check the door is locked, even though you know it is.
• Trouble with “no”. You take on more than you can manage, because refusing feels worse than being overloaded.
• Rest that doesn’t rest. A day off is filled with errands or with guilt that you ought to be doing something.
• The post-mortem. After every conversation you go over what you said, how they looked at you, what they must have thought.
• A body permanently on standby. Tense shoulders, a clenched jaw, shallow breathing, a stomach that speaks up before every important day.

From the outside, the picture is different: punctuality, preparedness, a smile, a reply to a message within a minute. It is precisely this gap between what others see and what you carry that lies at the heart of the term.

Achievement as a defence

Why does anxiety show up as paralysis in some people and as remarkable productivity in others? Part of the answer is more than a hundred years old. In 1908 the psychologists Robert Yerkes and John Dodson described what we now call the inverted U: up to a certain point, arousal improves performance; beyond that point it begins to impair it. A little tension sharpens you. People with high-functioning anxiety often live at the top of that curve — and fear that if they ease off at all, they will fall off it.

But the more important part of the answer is emotional. For many people, work is a way of regulating anxiety. When you are working, you are in control. When you prepare one more spreadsheet, check one more figure, answer one more message, the tension eases for a moment. That relief is something the body quickly recognises and remembers. Psychologists would say that achievement has become a safety behaviour: something that calms fear in the short term but keeps it alive in the long term, because you never find out what would happen if you didn’t do it. I have written more about this mechanism in Anxiety and avoidance.

Thomas Borkovec, who spent decades researching worry, suggested that worry itself is a kind of avoidance: when we turn things over in words, we avoid the more direct, bodily images of fear. With high-functioning anxiety this often doubles up — worry leads to a plan, the plan leads to work, the work leads to brief relief. The circle closes and starts again.

In relational family therapy, in which I am training, we would also ask: where was this way of being learned? Often in families where love was quietly tied to achievement, where one parent was unpredictable and the child made sure everything was under control, or where the child was “the one who never caused any trouble”. Back then, achievement was a clever solution. Today it remains a habit that no longer needs to be paid for at such a high price.

Perfectionism: when “good enough” feels dangerous

It is almost impossible to talk about high-functioning anxiety without mentioning perfectionism. Since the early 1990s researchers have distinguished between several of its forms. Paul Hewitt and Gordon Flett described self-oriented perfectionism (you demand perfection of yourself), other-oriented perfectionism (you demand it of others) and socially prescribed perfectionism — the belief that others expect perfection from you and will reject you if you fall short.

It is this last form that is most closely linked with anxiety and depression. And it is rising: a 2019 meta-analysis by Thomas Curran and Andrew Hill, covering students in the USA, Canada and the UK, found that socially prescribed perfectionism increased by roughly a third between 1989 and 2016.

Perfectionism intertwines with high-functioning anxiety in a particular way. It is not simply the wish to do something well. It is the feeling that a mistake is dangerous — that it will reveal something about you that you need to hide. So “good enough” is not a relief but a risk. I have written more about how perfectionism links up with endless overthinking in Perfectionism and overthinking: two sides of the same fear.

The body keeps its own account

The mind can pretend for a long time that everything is fine. The body cannot. Constant readiness means that the stress system — the axis between the hypothalamus, the pituitary and the adrenal glands, together with the sympathetic nervous system — is often switched on for longer than it was designed to be. The neuroendocrinologist Bruce McEwen introduced the term allostatic load for the wear and tear the body accumulates through prolonged adaptation to stress. It is not one dramatic event, but a thousand small activations that never fully switch off.

For people with high-functioning anxiety this often means:

• sleep problems, especially waking in the night with thoughts that start racing immediately;
• tension in the neck, shoulders and jaw, and headaches;
• digestive problems that get worse before important days;
• frequent colds or tiredness that shows up precisely when you are on holiday.

That last point is typical. Many people say they fall ill on the first day of their holiday, or that the first quiet weekend after a demanding period “knocks them out”. Some even have their first panic attack only once things have calmed down — I wrote about this in Why panic arrives only once things calm down. The body was waiting until it was safe enough to show what it had been carrying all along.

Important: physical symptoms can have other causes too. If you are troubled by your heartbeat, pain or digestion, see a doctor first. Anxiety is not an explanation that should ever replace a check-up.

Why the people around you don’t notice

One of the most common questions I hear from people who recognise themselves in this description is: “Why doesn’t anyone see it?” The answer is simple and a little sad: because you have worked very hard to make sure they don’t.

People recognise anxiety by avoidance, withdrawal, tears, failure. With high-functioning anxiety these signs are absent or well hidden. In their place are signs that society rewards: punctuality, preparedness, taking responsibility. Your boss sees a reliable colleague. Your partner sees someone who has everything under control. Your parents see a child who “never gave us any trouble”. Being praised for the very thing that is exhausting you is one of the most confusing experiences there is: it is hard to ask for help with something everyone admires you for.

The conversation might go like this (composite, not a real person):

“I don’t understand why you’re so tired. Everything’s going brilliantly for you.”
“That’s exactly why. Things going brilliantly costs me everything.”
“But you never said it was hard.”
“Because I didn’t know I was allowed to. I thought you loved me because I cope.”
“I love you when you don’t cope, too. You just have to tell me.”

This conversation often happens late — when signs of exhaustion are already showing. But simply saying it out loud opens up something new: a relationship in which you don’t have to keep proving yourself.

There is one more reason why others don’t notice: often you don’t either. When anxiety has been part of how you function since you were young, it doesn’t feel like anxiety but like character. “That’s just who I am. Responsible.” Only when you compare what a day costs you with what it costs others, who get through it with less effort, does the difference become visible.

From high-functioning to burnout

The circle I described above has one unfortunate property: success doesn’t stop it. When you succeed at something, the anxiety settles for a moment, and then the bar goes up. Praise becomes the new expectation. Next time it has to be even better.

This circle can run for years. But the energy it consumes is not endless. Research links perfectionistic concerns — fear of mistakes and the sense that others expect perfection — with a higher risk of burnout. A 2016 meta-analysis by Hill and Curran found that it is these concerns, more than high standards in themselves, that predict exhaustion.

The transition is often barely noticeable. First, you lose your pleasure in the things that used to fill you up. Then comes cynicism, irritability, the feeling that no matter how much you do, it is never enough. In the end the body simply says no. If you recognise yourself here, I recommend Burnout is not laziness: signs your nervous system is asking for a break and the burnout self-check in the knowledge base.

Small things can also warn you about this transition: when coffee no longer helps, when you need a glass of wine every evening to settle, or when you can only fall asleep with your phone in your hand. Everyday aids like these often quietly amplify anxiety — that is the subject of Caffeine, alcohol, screens and sleep: everyday amplifiers of anxiety.

Exercise: one day with a deliberately lower bar

This exercise is not meant to make you less responsible. It is meant to help you discover something your anxiety would rather you didn’t: what happens when you don’t do something perfectly. It takes one day and a few minutes in the evening.

1. Choose one small task where the risk is low: an email you send after reading it once, a report without the final check, dinner without all the ingredients.
2. Write down in advance what you are afraid of. “They’ll notice the mistake.” “They’ll think I’m careless.” Rate how likely it feels, from 0 to 100.
3. Do the task to “good enough” and let it go. Notice what happens in your body. Don’t try to stop the discomfort — just notice it.
4. In the evening, write down what actually happened. Did anyone notice? Were there consequences? How likely does the fear seem now?
5. Write down what you did with the time you saved. Even if you just sat there. That is part of the exercise too.

If the discomfort is strong, that is useful information, not failure. It tells you how tightly your sense of safety is tied to being flawless. After a few days you can repeat the exercise with a slightly bigger task.

Where this description doesn’t fit

I want to be honest here, because the term high-functioning anxiety can also be misused.

Not all conscientiousness is anxiety. Some people are precise, organised and hard-working because it gives them satisfaction, not because they are afraid. If you can leave something unfinished without much unease, rest without guilt and a mistake doesn’t cost you your sleep, this is not anxiety but simply the way you work. It doesn’t need fixing.

The term can blur more serious distress. Because it sounds almost flattering — “high-functioning” — people readily adopt it instead of saying “I have panic attacks” or “I haven’t slept for months”. If your anxiety includes panic attacks, thoughts of death, complete sleeplessness or drinking to calm down, that is a reason to see a doctor, not just to try self-help. If you are having thoughts of suicide, in Slovenia you can call the crisis line Klic v duševni stiski on 01 520 99 00 (every day from 7 pm to 7 am) or the Samaritans’ helpline on 116 123 (24 hours a day), and in an emergency 112.

It is not all down to the individual. Some workplaces are built so that constant availability is a condition of survival. In that case anxiety is not only your inner story but a reasonable response to unreasonable conditions. Therapy can help you, but it cannot replace a change in the conditions that are wearing you down.

What can help — and when to seek support

The first step is often the hardest: admitting that something you are good at also hurts you. People with high-functioning anxiety rarely come to therapy because of the anxiety itself. They come because of insomnia, tension in their relationship, or because their doctor told them to slow down — and only later does it become clear what lies underneath.

In therapy we don’t work on making you less capable. We work on making your capability a choice rather than an obligation. This often includes:

• recognising the moments when work becomes your way of calming down;
• exploring where you learned that your worth has to be proved;
• learning to stay with discomfort without immediately “solving” it with action;
• working with the body: breathing, rest, movement that isn’t yet another task;
• changes in relationships — so that the people close to you can also see what you have been hiding.

It helps to know the concept of the window of tolerance: the range of arousal in which you can think, feel and respond flexibly. People with high-functioning anxiety often live close to the upper edge of that window and are so used to it that it feels normal.

If you notice that your anxiety is tied to a sense that you must hold everything together, you may also find Panic and control: why it strikes the person who holds it all together close to home.

What to remember

• High-functioning anxiety is not an official diagnosis, but a description of a shape anxiety can take: control on the outside, an alarm on the inside.
• Achievement can become a way of regulating anxiety — it calms you in the short term but keeps the fear alive in the long term.
• Perfectionism, especially the sense that others expect perfection, is closely linked with anxiety and burnout.
• Others don’t notice because the signs are rewarded — and often you don’t notice them yourself.
• Physical symptoms, panic, insomnia or drinking to calm down are reasons to see a doctor and talk to a professional.
