Do you ever get really depressed?

I am sad. Not ordinary sad, it's some profound kind of sadness. I don't quite know how to describe it. But it's real, so very real to me. My mind wanders and if not that, I am unconscious but even that is not for very long. In fact , on a good night, I can only get 2 hours of sleep. These nights are rare. On top of it all, my town is a miserable place. I wander around at nights but never out of desire. It doesn't serve some kind of purpose. It is simply a necessity although I don't quite know why. When I'm around my "friends", I morph into an alien. It makes me so very sad.
