What's the best antidepressant for anxiety and stress?  I've tried Xanax and Klonopin but it's not really working.  I have awful health anxiety.  It's causing me to have panic attacks all day.  I get tightness in my chest, can't breathe, want to jump out of my body.  I also get loose watery stools when it's really bad.

Had all kinds of tests done over the last 3 months.  CBC, ESR, CRP, ANA tests for autoimmune disorders, thyroid tests (TSH comes up alittle high but T4 is normal), I even had stool tests and a colonoscopy with biopsys, all came back normal. I had a CT scan of my abdomen, also normal. 

I need help.  I can't stop stressing and my stress keeps causing my issues.  What's the best antidepressant?  Is Zoloft good?

Anyone else get tummy issues and watery shits with their anxiety?  

I'm 36 year old male.  No prior health issues
