Thanks I need to start seeing a therapist again, but it is hard to feel hopeful enough to invest the effort. I suppose my lack of sex drive might be caused by depression. Normally I ride my exercise bike every day to control the depression, but for several months I've begun to feel like exercising only fixes the symptoms of depression and deep inside I am still very unhappy. That roughly corresponds with the sudden loss of sex drive. Of course my sex drive has been dropping gradually for many years, but to have it disappear entirely was a surprise.

I hope this might help somebody else. I was very happy this morning, because the depression was gone. I thought my depression was not actually depression but only sexual frustration that I no longer cared about. Now I'm not sure if that was right. I was feeling fine until this afternoon and then it seemed like a balloon deflating all of the sudden. I feel really tired. Maybe I have a blood sugar problem, but the doctors say I'm fine.

Anyway, thanks again for the reply.
