Hey, I am a 16 year old girl, I jsut recently found out that I have panic attacks, mine were a lot like yours, mine started when a good friend of mine killed himself, I was afraid to go out, go to school, or go well, anywhere, im also afraid of the dark, and to be alone.
I definetly think that you should go to the meeting though, I didnt want to go to mine, but I was perscribed luvoux, and it has helped a lot.
I hope that you feel better , and I hope that you make the desision that you feel is right
