Hello and welcome,
I agree with Lyn and wonder if you have ever been evaluated for your diarrhea by and Gastroenterologist ?
I know some people are plagued with diarrhea where as others get upset stomachs when their anxiety is high. Please do get a good physical.
I have read some people's posts that have had luck going on an Antidepressant for the anxiety and D.
You deserve relief from this problem so please do contact your Dr. We are all here for you.
