Hm, I'm not that well read on anxiety disorders, but in my particular case it seems to be biological -- a chemical disbalance, one aspect of which was related to the acidity of the foods I ate. A change in diet helped alleviate this problem and an addition of omega 3&6 fatty acids in my daily intake seems to be holding them at bay entirely, though they begin to return if I deviate from my current regimen.

Perhaps you could consider a change in your diet to reduce the risk as well? It's the least invasive method of handling the problem. A consultation with a dietician may be in order though -- a person's unique metabolism is a finicky thing. In my case it was mostly "self medication" thanks to advice I've read on the net (regarding omega3/6) and general diet advice.from my mother.

Hey, I'm not sure how I ended up here, but apparently I'm following you since this post was on my feed. I just wanted to chime in to say something comforting and supportive as I too have suffered from panic attacks and anxiety and know how debilitating it can be. But I really believe that we have control in how we want to experience the world. I know what it's like to be afraid of losing control (I also still battle with this from time to time, yet it is getting better by day because I am actively working to change my beliefs and catch and stop myself when my thoughts start to spiral.), yet I think that there is so much hope and we don't have to let those anxious thoughts rule our lives. 
Not that I know any better than you do, but I just wanted to offer some support as it's kind of nice and comforting to bump into someone who has had the same kind of experience that most people do not understand.
