I shake when I have an anxiety attack. I end up telling people I'm too cold (which usually isn't too much of an exaggeration). I've taken my blood pressure and heart rate during anxiety attacks as well and they increase big time.

I'm not exactly sure how I do this but when I am in class or somewhere I have to be professional, I quickly divert my mind to other things and sort of put the feeling off for the moment. Then when I am free, I take a walk outside, or go to the bathroom and cry if I need to. I'm not sure if that's a good thing to do though...
