On Depression

I once read a book about depression titled The Beast. It is an accurate representation - at least for me, anyway- of what it's like to have depression. Things will be going along fine, and then BOOM. The beast moves in for a while.
Last night, for example, I started crying while watching ABC's Nightline with Ted Koppel. There was this piece on the poverty and starvation in Niger. I couldn't change the channel, but I couldn't stop crying, either. I've been in a funk ever since. Didn't want to get out of bed this morning. Didn't want to do anything. Still don't.
Sometimes the world seems like such a cruel place.
