People talk about hot flashes, nausea, sweating, IBS, heart palpitations etc.

I don't really get any of that. In fact I felt guilty telling my therapist that I was having "panic attacks" when I wasn't even breathing heavily or shaking or anything. 

I mean I was terrified, and I felt numb and the back of my neck was hot, and that was it. That's as far as my anxiety goes physically, so it's almost like I feel insecure, like I'm not "anxious enough" to have anxiety (and yet my thoughts are OFF THE RAILS sometimes). Does anyone relate?
