Sorry you're having such a bad time.
Have you looked into LDN, low dose naltrexone?
Do some research on LDN - low dose naltrexone, you can search this forum as they are several threads on this. I can tell you it works!
Here's the Penn State research done by Dr. Jill Smith with LDN and Crohns Patients.
