Why panic attacks feel like an emergency

It arrives out of nowhere. Your heart pounds, your chest tightens, your hands tingle, the ground feels unreliable. And with the sensations comes a certainty, absolute and immediate, that something catastrophic is happening. A heart attack. You are going to faint, or be sick, or lose control in front of everyone.

It passes. The tests come back clear. The doctor is reassuring, and part of you is relieved while another part is sure they have missed something. Because you were there. It did not feel like anxiety. It felt like an emergency.

It feels that way for a reason, and the reason is also the treatment.

One specific mistake

Panic runs on a specific, identifiable mistake, and once you can see it, it stops being mysterious. A harmless bodily sensation gets read as a catastrophe. The reading sets off the alarm. The alarm produces more sensations: the heart goes faster, the breath changes, the muscles tense, the head swims. And those new sensations confirm the catastrophic reading, so the alarm fires harder. Within seconds you are in a loop where the fear is producing the evidence for itself.

The sensation that starts it is often not even a situation. Caffeine. Heat. Standing up too quickly. A poor night's sleep. A skipped heartbeat that everyone has and nobody notices. The trigger is a feeling, not an event, and the feeling gets misread, and the alarm does the rest.

Why the tests are always clear

This is why the medical tests come back normal, and why the reassurance does not hold. Nothing is wrong with your heart. What is happening is your body's alarm system firing at full strength in the absence of danger. It is deeply unpleasant, and it is not dangerous. People do not faint from panic, because panic raises blood pressure rather than lowering it. Panic does not cause heart attacks. And it always comes back down on its own, because the alarm cannot sustain itself indefinitely.

You know some of this already, and you have found that knowing it makes no difference in the moment. That is because the alarm makes the mistake, not the part of you that knows things, and the alarm is retrained by experience rather than by information.

The second problem

Then the fear of the fear begins, and for most people this becomes the bigger problem. You start avoiding the places where it happened, or where escape would be hard: the motorway, the supermarket, the gym, the train. You carry water, or medication, or stay near the exit. You sit down when your heart goes, check your pulse, leave early. Your life gets smaller around a thing that has not actually happened yet.

Each of these safety behaviours brings relief, and each leaves the belief intact. If you sat down and nothing happened, the sitting down gets the credit. You never find out that nothing would have happened anyway.

What treatment does

CBT for panic disorder is what NICE recommends. We map your version of the loop precisely: which sensation, which prediction, which safety behaviour. Then we test the prediction rather than argue with it.

That includes interoceptive exposure: deliberately, in a controlled way, bringing on the sensations you fear, so you can find out what they actually do. It sounds counter-intuitive, and it works, because it is the first time your alarm gets to experience the sensation without the catastrophe. We also unpick the safety behaviours, and then we get back the places you have been avoiding, in a graded way you control.

Panic often responds quickly. Many people see meaningful change within 6 to 12 weekly sessions. If you have not had unexplained physical symptoms checked by a GP, I will ask you to, because good therapy does not skip the medical picture. Once that is clear, we can treat the sensations as safe with real confidence.

If the emergency keeps arriving and the tests keep coming back clear, there is more on how I treat panic disorder, and on the wider picture of anxiety it belongs to.
