I've fallen into terrible depression. Like I don't sleep or eat or talk to anyone anymore. I lay in my bed and cry about everything. As much as I want to get out and fight off my depression I can't. I go to work and avoid everyone. Then come home and go to My room and stay there til I have to use the bathroom. I eat maybe once a day if I'm lucky. I don't know what to do anymore. any tips or advice?
