I have suffered from anxiety since I was about 19, on and off and from what I can tell the bad anxiety
comes typically when I am dealing with a lot of stress.
The first anxiety
attack I had was when I was stuck on a subway. Underground for about 40 min,started thinking the worst;fires, crashes, not being able to get out. After that I did not use the subway for 8 years. Back to using the subway again now. At the start it was hard but I got over it.
