I was diagnosed as manic depressive in 2007. This is a progressive biochemical disorder from which I've evidently suffered for a very long time, perhaps even since adolescence, and which had reached a grave critical mass in recent years. I am currently under treatment, on meds that my doctor and I are fine-tuning, and I am slowly learning how to cope more efficiently and constructively than I have in the past. I mention the bipolar issue because I approve of the movement of sufferers who are "outing" themselves, discussing the disorder publicly, and in this way working to remove the stigma that surrounds it.
For first-rate information on bipolar disorder, consult the following web sites:
National Depressive and Manic Depressive Association
National Institute of Mental Health
I also highly recommend the outstanding book Manic: A Memoir by Terri Cheney as well asThe Years of Silence Are Past by Stephen P. Hinshaw. Further, I'd suggest you check out all the various, absolutely essential books written by Kay Redfield Jamison, professor of psychology and behavioral sciences at Johns Hopkins University School of Medicine. Most particularly - An Unquiet Mind: A Memoir of Moods and Madness as well as Night Falls Fast: Understanding Suicide.
