I took Prozac for a while several years back, and it did stop the depressive feelings... but it also made me feel real numb, which bugged the living hell out of me. I wasn't sure why it bothered me so much, but I think it's because of this: without emotional sentiment, things mean nothing. Lots of things felt that way - where I was living, what I was doing, my day-to-day existence. My drives have usually been pretty damn low; I don't often feel compelled to do things. (I wish I could figure out what my drives are.)
If you don't care, and aren't compelled, what left is there?
Sigh. I wish my emotions would stop whirling about so much, and that I could figure out what they were. Maybe tomorrow will bring new insight...
