Ah depression....its the worst, the worst to treat, the worst to have, the worst to deal with. At least with every other mental health disorder something can be done. Antidepressants are terrible, and they don't even work ...
My advice would be to get some exercise, climb out of the hole and force yourself to do something active for 1 hour.
Also, deep anger and rage is a warning sign. But it doesn't sound like you've made it that far yet.
Just stay away from drugs for a bit. They just make it worse.
