Have you tried medications for the anxiety? Aside from the usual suspects, there are a lot of other drugs that will help calm that adrenaline down, like most of the anti-hypertensives.

As for being a crazy person and just broken -- whch I often feel about this -- here's a little something I learned recently: once you've got that whole adrenaline system all ramped up with anxiety, it takes a while to reset. So, every time you restress it, it's going to overreact until it has a chance to go back to sleep long enough to reset itself to baseline. That can happen, though. It just needs some way to turn itself down long enough.

The problem, of course, is that there's a feedback mechanism between the physical part of the anxiety and the psychological part. Once you learn that this or that brings on all those physical symptoms, your brain will lay down pathways to the fear circuits. That's learned behavior, though, and it can be unlearned. It will take a while, there's no doubt, but it will happen. The two conflicting techniques are immersion therapy -- which, personally, I think would break me into tiny pieces -- or something I can't remember the name of which works on reassuring you by small steps. For instance, say you're afraid of spiders, they might start out by showing you a picture of a spider, then work up to showing you a spider in a jar, etc. The basic idea is to take small steps towards making you more comfortable with whatever you're afraid of. My guess is that one of the anti-hypertensives combined with that second type of therapy would be great for overcoming many of the common anxiety disorders.

Depending on your diagnosis, by the way, there's new evidence out there about using a calcium channel blocker called verapamil as a mood stabilizer in women. You might ask your doctor about it, since it should also lower your physical response to anxiety.

I hope that helps. Good luck.
