Murrough,
Its nice to meet you, so to speak. I can relate to your experiences. My anxiety and panic attacks actually started when i was almost finished highschool. They went away for over a year, and returned when i was finishing university and begining to work full time. I've often thought that they're a result of some sort of dysfunctional reaction, or preparation, for impending change. Does that make sense? You know your life is going to change, and aren't ready?
I think you'll find that most anxious people do not cope well with change (Many whether its good or bad). I am one absolutely. ANY change can set me off. People with anxiety live in a very delicate balance between being normal, or panicky.
As for how to make panic attacks go away, I think we're all still looking for these answers. Try not to fear the panic, realize that it will run its course in due time, and let it. You may find that you're panicking b/c you're afraid to panic (at least that's what i've learned).
Anyways, just keep reading the discussions here, you're bound to find SOMETHING that makes sense to you.
Keep in touch
Beth
