I agree that getting advice on the internet isn't the best idea, but might as well post my suggestions.
Don't let yourself sleep in. Try to be doing things all the time, and by that I mean real things, not playing video games, watching TV, or messing around on the computer.
If you have any groups you could volunteer in, do that. Don't work, work will make it worse. Volunteer. The difference is important for this.
Take long walks, preferably far away from cities. Go to a park or a forest or somewhere, pack a sandwich and a bottle of water and nothing else, and just walk. Think, but don't stress over life issues.
It really would help if you could post just a general explanation of why you're depressed, it doesn't need to be specific.
