The seat near the exit

It starts with something completely reasonable. You take the aisle seat instead of the middle. You park where you can leave easily. You go to the smaller supermarket instead of the big one.

None of those is a symptom. Each one is just a preference, and a sensible one. That is exactly why they are so hard to see.

A year later you notice you have not been to the cinema. Not because you decided to stop — you just kept having reasons. And each reason was true.

The world does not shrink in one move. It shrinks in choices that each make sense on their own.

Here is the mechanism underneath. Every time you avoid something and feel the relief that follows, your nervous system files a lesson: that was dangerous, and leaving kept me safe. It does not matter that nothing bad happened. Nothing bad happening is exactly what gets recorded as proof that the escape worked.

So the fear does not fade with time. It gets confirmed, quietly, one sensible choice at a time.

The useful thing about knowing this is that it changes what you look for. Most people track their panic attacks — how many, how bad. That is the wrong measurement. The number that actually predicts how your year goes is how many places are still on your list.

Try this, and be honest: name the things you used to do that you have not done in the last six months. Not the ones you lost interest in. The ones you still want.

That list is the real map of this. And unlike the attacks themselves, you can walk back onto it — in order, at a pace that does not break you.
