Hey Sue,
Wow! That's a tough question. As I read your post I tried to think of what I do. When it happens to me I find a quiet place to sit and I breathe, pray, read or watch TV. Basically I try to distract myself.
I am sorry your having a tough time. Lately I have been a little lazy about this disorder. I haven't been praying or reading as much and those things work for me. I have been exercising and that helps. I hope you are feeling better soon. Keep us posted.
Take Care
