I'm 36 years old with a history of bad health anxiety. I recently started noticing changes with pooping.  If I'm not anxious I'm usually fine but when I'm really stressed out I get all kinds of different varieties.  Sometimes small pieces, sometimes watery and loose, sometimes normal.  My anxiety is really bad now and I'm just getting anxious about the poop which causes weird poop and then it just never ends
 
I recently had a physical...CBC metabolic ect...all normal.  I had tests for inflammation like ESR and CRP, I got checked for IBD antibodies, all clear.  I even had a CT scan of my abdomen and it said normal, no inflammation changes, and poor distended left colon...which my GI said can be normal.  

I'm worried about bowel cancer or something.  My GI said if I'm that worried we can do a colonoscopy but I'm terrified of doing that so I want to avoid that like the plague

Anyways...anyone else get anxiety weird poops?
