Wow...same thing happened to me. 4 years ago when I started having this pain and I was sent to a psychiatrist although I must admit that I did become suicidal as the pain was relentless and wouldn't allow me a moments rest. As first it was thought I had crohn's and to date I still have no diagnosis except possible nerve pain or adhesions or endo or (insert whatever here). Regardless, anti-depressants work on pain by "turning down the volume" as my doctor would say. I was on Celexa for 3 years and although I still had pain, it helped me immensly. As for the psychiatrist, he was NO help at all as he tried to enter my childhood and other mumbo jumbo into the picture which had nothing to do with my situation. Anyways, just wanted to let you know I understand.
Hope you feel better
