Some 2 years ago I had my first panic attack, I mostly had them during the night, and to avoid attacks I went out every single night, yes, 7 nights a week.
With me it had to do with opressed fears and memories.

The attacks got worse and I went to my GP who gave me a diazepam prescription.
One pill to make the attack go away.
Further more I got diagnozed with PTSD.

After some months I could better deal with things, I knew what to do when I felt it comming.

Right now I'm doing fine, hardly no attacks and in fact, most of the time I am feeling happy.
