I'm 31 and I've had 2 mild panic attacks in the past.. I'd rate then both about a 3.5/10.

A few days ago I had my first full blown 10/10 and had an ambulance called. It wasn't a build up, it went from zero to 100 within 2 seconds, and lasted for 2 minutes and it was almost every symptom of a heart attack.

Since that day I've managed to fight off at least 2 panic attacks each day. I can feel them coming on and manage to calm myself down before it gets out of hand by recognising they're not dangerous.

For those of you who experienced this, did you end up getting smaller waves of panic attacks after your first big one? how long did it last?
