I know the desire to lie in bed all day or to just watch TV---even reading takes too much energy.

But--- you are in university, right? Please don't let this opportunity go to waste. You may never get the chance to do it again. Life might just happen and sweep you away with the need just to survive. I wasted my opportunities in college so I know what I'm talking about. Try to do just one thing. Don't think about all the things you need to do. Think only of the one thing you choose to do right now.
Are you seeing a professional? If not then you must seek one right now! It's almost always necessary to get help to get through depression. It's not something that will just go away. There are things that can help you cope so life will be easier to handle. I'm sure your school has a counseling center. Go see them. If they don't have one then look up your city's helpline numbers and call them.
Please don't let this trouble ruin your college career. It's so important.
I hope you feel better soon and Good luck. Keep posting here. We'll be interested to know how you are
