Dear fantome,
I can certainly identify with what you wrote although our situations are somewhat different. What helped me most was exercise and a low carb diet. This is not advice to you though since I am thoroughly unqualified to give advice that you or anyone could or should reply upon. Perhaps a consult with a physician might be helpful. I don't know. So sorry I cannot be helpful to you in this. I can feel for what you are going through and my heart goes out to you.
Sincerely yours, Yao Wen
