Depression Support Group
Depression is a real and debilitating condition that is often misunderstood by family and friends. Its meaning can range from a prolonged period of sadness to an actual mental illness with specific symptoms. Find and share experiences with others who are going through the same struggles.

Instead of quitting school perhaps changing to Online Classes, and maybe taking only 2 or so, this would give you less of a heavy load and lessen the stress of having to go to class and be around so many people. It would also make you still have to get up and get your work done.
Try to never give yourself a clear schedule of nothing to do, its so easy to be sucked into that life and just laying in bed all day or sitting on the couch staring at a TV....you don't want to go there.
Have you checked with your local Hospital or your Pdoc or Counselor to see if there is a depression support group that meets anywhere in your town that you could go to. So you could meet people that have similar circumstances in real life, that might be helpful and give you people to talk to about what your going through.
