I've been in this situation for a while and I would recommend you this: do not stop. Do something, even the stupidest thing, but please do not remain alone in your room. You need to do something, call someone you love to talk about your situation, ask for help to a college counselor. In other words, move. I mean, even if you don't know where you are going to, it's better than not moving at all. I've felt like you for months and I didn't know what would have helped me to get out of that situation, I just tried and tried and tried. I knew that it was better than doing nothing. Situation now is way far better, but I needed to fight, and still not so good, but I know that if I stop than I'm lost. Best wishes
