I wholeheartedly suggest a combination of diet and exercises (many can be made at home). I recently discovered Nerd Fitness, a blog directed to nerds that is getting some attention (Steve Kamb, the man behind it, gave talks to Google and FB) and it is pretty much changing my life.

I am not saying that this is the cure, but from my experience with depression I think that much of it is related to physical activity and general welfare. And a good diet (paleo works very well for me) and fitness can help a lot.
