Excessive sleep was a big problem for me years ago when I had a major episode. I don't have any immediate advice on that front, since it is really an effect of the depression.

Going for a degree can be tough enough. I'm sorry that you are having so much trouble motivating yourself to get there.

There's been a few other threads here and there about getting going in the morning.

I hope things get a little easier for you.
