I have suffered from this for many years as well. I have several suggestions that MAY help. First, is don't have unwavering faith in your doctor. If he's getting worse dispite his and and doctor's efforts to get better investigate trying another Doc. Secondly, I found group therapy to be very helpful to me. There is something about sharing and the understanding of a group that was very helpful to me. You can do this thro a Doc, a hospital or community groups like Emotions Ananamous. If he drinks (many of us do) go to AA as well. Think about some alternative approaches also. Get a book on some of these like message or aroma therapy. I have not tried them but I hear with some people the work very well. Good Luke.
