Fear of fear: how panic learns to return

“I am not afraid of the shop. I know nothing will happen to me in the shop. I am afraid of that sensation. That my heart will start up again, and that I will stand there like an idiot again.”

This is one of the most common sentences I hear from people after a few panic attacks. And it is accurate. After the first attack the fear moves. You are no longer afraid of what happened — you are afraid that it will happen again. The object of fear is no longer the world outside, but your own body.

In the literature this is called fear of fear, and it is precisely this shift that turns a single attack into a repeating pattern. The attacks would not sustain themselves. What sustains them is what you do between them so that they will not happen. In this piece I describe the mechanism — how panic learns to return. How to approach it is a separate subject and deserves its own piece.

What fear of fear means

By definition it is a fear of the bodily sensations of arousal and of their presumed consequences. Not of a heart attack as an event in the future, but of the pulse you can feel right now, because in your experience that pulse is a forecast.

The distinction matters, because it changes where fear can appear. If you are afraid of lifts, you are safe everywhere there are no lifts. If you are afraid of your heartbeat, there is nowhere you can go without it. The body is the one thing you take with you every time.

This is also why panic spreads so readily. The first attack was on a bus, then it turns up in a shop, then in the office, and it feels as though the fear is “catching” new places. It is not catching places. It travels with a bodily sensation, and that sensation is the same everywhere.

How a bodily sensation learns to forecast terror

During the first attack a piece of learning took place that you did not choose. The nervous system linked two things that happened together: an innocent bodily sensation at the start, and the terror that followed. From then on the sensation is no longer only a sensation — it becomes a forecast.

Researchers call this interoceptive conditioning. Outside this field you know the same mechanism from other stories: if you once become badly ill after a particular dish, your stomach turns at its smell years later, even though you know perfectly well the food was not to blame. Your body has done the same thing with your own pulse. This is why knowing rationally that an attack is not dangerous does not erase the reaction. Knowledge and conditioning are two separate systems, and the first does not switch off the second.

Sensitivity to bodily signals is not the same in everyone

Here is something that explains why some people develop a disorder after a first attack and others do not. We differ in how much bodily sensations unsettle us in the first place. One person climbing stairs thinks “well, I am unfit” about a racing heart; another thinks “what if there is something wrong with my heart”.

This trait is measured with an anxiety sensitivity questionnaire, and it has turned out to be one of the few predictions that genuinely work in advance. In a well-known study, military cadets completed the questionnaire before five weeks of very demanding training. Those with higher scores had substantially more panic attacks during the training — and the link held even among those who had never had one before. Sensitivity, then, is not a consequence of attacks; it often comes before them.

This is not fate and it is not a flaw of character. It is a leaning that can change. But it is useful to know about, because it explains why two people with the same experience end up somewhere different.

Anticipatory anxiety: the attack that lasts all week

The most exhausting part of panic disorder is often not the attacks at all. There may be one attack a month. Between them, something else runs: anticipation.

You wake up and the first thought is whether today will be a good day. Before a meeting you work out where you would sit and how you would get out. When you accept a dinner invitation a fortnight away, something in you calculates that same evening how far the restaurant is. Attacks last minutes; anticipation fills the whole space between them. Many people tell me they could bear the attacks if only that quiet, constant calculating in the background would stop. That is not weakness — it is the logical consequence of a nervous system that expects danger and prepares for it. I have written about a related, though not identical, phenomenon in the piece on going over thoughts again and again.

Watching the body, and what it finds

Once the body becomes the site of danger, attention turns inwards. People with panic check their bodies more often than they realise: feeling for the pulse, testing whether a deep breath goes all the way in, swallowing to check the throat still works, watching whether vision is somehow odd.

The trouble is that the body is always doing something. If anyone listens closely enough, they will find an uneven beat, a tightness under the ribs, pins and needles in an arm that was in an awkward position. In a person without panic this data never reaches awareness. In a person with panic each item becomes evidence that something is starting. So the searching does not calm anything — it produces material for the next loop.

The same goes for smart watches and heart rate monitors. Many people put them on precisely in order to feel reassured, and then check the number several times an hour. The device does not settle the pulse, it only displays it more often — and every reading above a hundred becomes an event that needs explaining. For some people the single most useful step is to put the watch in a drawer for a few weeks.

Safety behaviours: what they actually do

Everyone with panic eventually assembles a list of things that help. Sitting near the door. Having a tablet in your bag, even if you never take it. Ringing your partner so they stay on the line. Leaning on a shelf. Buying water. Leaving the shop before it builds.

All of these are understandable and genuinely do help in the moment. So I will not call them mistakes. I call them safety behaviours, and their peculiarity is that they are useful in the short term and expensive in the long one.

They are expensive because they prevent you from being convinced otherwise. If you leave the shop the moment the sensations build, the attack indeed does not develop. But you do not learn from this that there would have been no attack anyway — you learn that you prevented it. Next time, leaving is even more necessary. So a safety behaviour becomes more needed with every use, even though it appears to be solving the problem.

Why relief strengthens fear

The mechanism is really quite simple, and that is exactly why it is so stubborn. Whatever brings relief gets repeated. The relief that follows a retreat is strong and immediate, so retreat becomes established faster than almost any other habit.

This is why people often describe getting worse even though they are “trying harder and harder”. The effort is aimed at prevention, and prevention is fuel. I have described a similar trap with worry in the piece on postponing worry: what works within five minutes is not necessarily what works within six months.

Why being reassured does not stick

People with panic often know more about panic than their acquaintances do. They read everything. They can list what the sympathetic nervous system does. And still, none of it helps in the shop.

The reason is that knowing and believing are not the same. The belief that a fast pulse is harmless does not come from an explanation but from experience. This is also why reassurance from outside has a short shelf life: a partner’s “nothing is going to happen to you” works for ten minutes, and then it has to be repeated. Asking for reassurance is really one more safety behaviour, only carried out by somebody else. I have written about stepping back from thoughts without arguing with them in the piece on cognitive defusion.

Where this explanation does not hold

The fear-of-fear model is a good one, but it is not complete, and I know of at least three places where it breaks.

First, it does not account for attacks that wake you from sleep. If you are asleep there is no body monitoring and no catastrophic thought, and yet the attack happens. There are explanations, but none as clean as the model for the waking state.

Second, the description easily turns into an accusation. When someone reads that safety behaviours maintain panic, they often hear: so it is my own fault. That is not true. These behaviours are not a choice but the most logical answer the system can produce at that moment. Guilt shifts nothing here, and it often adds a layer we then have to work with separately — I have written about it in the piece on healthy and toxic guilt.

Third, sometimes panic is not the main story. If depression, alcohol misuse or a traumatic experience sits underneath it, working on the loop alone will not achieve much. And not least: when bodily symptoms have not yet been examined medically, caution is not a safety behaviour but common sense. The fear-of-fear explanation applies only once the physical side has been checked.

What this means for the way forward

If avoidance maintains the loop, then the direction of the work is fairly clear, even if uncomfortable: fear does not shrink because you argue it down, but because you allow a bodily sensation to finish on its own. That takes structure, gradual steps and someone alongside you — and it is the subject of another piece, not this one.

Something else is more useful here: make a list. Write down everything you do in one week so that an attack will not happen. The tablet in the bag, the seat by the door, the phone call, the water, glancing at your pulse on your watch, checking where the nearest pharmacy is. People are almost always surprised at how long the list turns out to be. That is the beginning, because a pattern cannot be given up until you can see it.

Alongside that list, one more thing is worth writing down: what it has cost you. Which places dropped out, which invitations you turned down, who has stopped inviting you because they know you will cancel. That second list shows how much room panic has actually taken, and it is often the one that finally moves people to arrange a session.

What to remember

Panic does not return because something is wrong with you, but because a bodily sensation has learned to mean danger. Between attacks that fear lives on as anticipation, as body monitoring, and as small safety behaviours that bring relief now and a higher starting point a month from now. This is not your fault and it is not evidence that you are weak. But it is a pointer: what maintains the loop is not the attack, it is everything you do around it so that it will not come. If you recognise your own list, you have seen the mechanism — and mechanisms can be taken apart.
