What causes sadness and depression?

[AnthroHeart]

I'm gonna say it's the anti depressants.

The anti-psychotic is probably worse. It totally closes down my 3rd eye.
But it keeps me sane. With all I've been through I've learned a great deal, and probably could handle being insane.

But the other day I was freaked out by my window curtains. I thought they were going to fall down and wrap me up in them and trap me.
