Dear Alice,

You should probably be more concerned for your roommate right now than for yourself. Her problems seem a lot bigger than yours. It's obvious that she needs a lot of help. Maybe instead of just sitting in the room with her while she sleeps, ask her to go out with you to see a movie or get some food. At first maybe she'll deny you but say it'll be good for her to get out and do something and have fun. Who knows, maybe you'll both feel better.

P.S. Your roommate also might be feeling a little depressed because she senses that you don't want her as a roommate. Just a thought.
