All I can suggest is to keep trying other doctors or perhaps naturopathy or other alternative , acupuncture?
Start totally fresh with new doctors , so less of a carry over from past office notes/opinions?
A symptoms journal or log of main issues with a clear description..might be helpful.

If psych is a possibility we have a sister site based more on that focus -
