The body notices first
The jaw, the shoulders, the stomach. They know something you have not thought yet.
Almost everyone who has had a panic attack describes the same sequence: the body first, then the fear, then the thought that explains the fear. The reverse of the order you would expect.
Which means that in the preceding days there were almost always signals, and they were physical: a clenched jaw on waking, shoulders that will not drop, a closed stomach at lunch. These are not consequences of the anxiety — they are its first form, arriving before there was a sentence to attach to it.
Learning to read them does not prevent the attack. It does remove the worst part, which is the sense that it came out of nowhere.
