I listened to this interview today with Terry Gross on NPR:
Writer Andrew Solomon's new book on depression, The Noonday Demon: An Atlas of Depression, (Scribner) came out of a 1998 New Yorker article. He draws on personal experience as well as interviews with patients, physicians, philosophers and drug designers.
He mentioned apathy as one of the symptoms. It seems to be a fact that one can experience some pretty crushing emotional feelings all at least in part related to various chemical consentrations in the brain and that can be altered, improved, by various drugs. There is a pon more to the issue, but if you really even close to feeling the kind of suicide contemplating apathy that is possible for some really a large number of people, you need to stick in your rational mind a realization that you may be suffering from chemicals rather than problems, and that you can get real help, even if the emotional mind thinks there's nothing you can do.
The guy wrote the book to give people knowledge on how help is possible.
I was there, once, too, at a point where there was nothing but black no exit hopelessness, nothing but utter meaninglessness. At the point I truly gave up I entered a state of pease and an end of grief. I don't understand it, but I know it happened to me and it happens to others.
Get into a dialogue with somebody responsible, a school psychologist, maybe, I don't know your circumstances, who can help you and provide sound judgment on whether you could use some help.
