The number of anxiety attacks seems to have been growing with me, so I wanted to pass along somethings that have alleviated some of the symptoms. Exercise - particularly yoga (even it if seems girly or kinda dumb), has been particularly soothing & help for a range of my symptoms. It helps me relax, and they even have poses that help with digestion.
I've also gotten involved with running. I used to dislike it, but now I absolutely love it. Being bed ridden for 3 months will do that to you I suppose. The real help is in forgetting though. You lose yourself in the run (or sometimes fast paced walk). You lose the anxiety. You lose the pain. You lose the feeling on edge. It releases endorphines. It provides me with reassurance that even though I 'think' I'm having heart problems instead of my gastritis, that reason can help intervene when I'm having attacks. I'll say to myself, "Ok, genius, if you're having a heart attack, how in the world did you just run 1+ miles, and felt great the whole time?" I try to do it everyday it doesn't rain or is too cold. I still do yoga everyday - even if for just 10 minutes in the morning.
If I were a doctor I would PRESCRIBE these two activities on a daily or at least every other day to EVERY person who suffers anxiety attacks. The only other thing that has helped me has been to pop a xanax during the most severe episodes.
Good Luck!!! And give it a shot!
