Oh jeez. Do you have a back yard or anything? Take one of those folding lawn couch things or even a hammock if you can score one and Go have a nap out in the sun
put some sun screen on and let yourself relax
Maybe read your favorite book outside or something. just get out and away from anything you can hurt yourself with.
Also sometimes the best thing you can do is confide in someone who can help you. Maybe he can get you a councilor that you can talk to or someone.
Good luck and take care
