Thanks for the responses!
Yeah, I have depression and insomnia, and I KNOW my depression plays a huge part in it. I am on depression meds and have been since I had a large bout of it a couple of years ago, and it has helped me tremendously, so I guess I figured it didn't have anything to do with my depression.

The classes I'm taking are awful, SO boring, and I am not at all interested in them. They're classes I have to take to work up to the interesting psychology classes I'll be taking later, so I think that plays a large part, too. They are terrible, in my opinion.
