Give me a diagnosis guess!?

Here’s the deal, all I want is a guess from you. I’ve had intense nausea almost everynight, trouble swallowing, constipation, rectal bleeding (I do have hemmoroihoids), admoninal cramping, and fatigue for about 5yrs now. What do you think it could b?
Here’s what I have tested negative for: so It’s NOT any of these things:
Peptic Ulcer
any form of IBD (crohn’s or ulcerative Colitis)
Celiac Disease
Gallbladder probs
Kidney Probs
Liver Probs or any sort of organ probs
Colon Cancer
Stomach Cancer
Polyps etc.

Ive had a colonoscopy a EGD a songram and a bunch of blood work, all came up normal
