I agree with the mood stabilizer idea. I have bipolar, and it sounds to me like what you have fits into that category.

My suggestion: See a regular doctor for a good physical evaluation to make sure your physical pain doesn't have a physical basis and then see a therapist again and a psychiatrist again and get yourself on a mood stabilizer and perhaps some other meds to get you more stable. Okay?
