This is all coming to an end soon. It would be better for you to take control now and get some help with your anxiety. Staying inside living on borrowed money is worsening your situation.
Does your college have a crisis center? There may be one in town. Anyway, call them. They will get you started down the path to mending.
I've withdrawn as well. Although I'm "going" to school on scholarship...I've chosen online classes. I don't want to tell anyone I'm not alright going outside. When I'm made to go out I freeze up and I feel like I cannot properly function. As if I may cry. Sometimes I do end up crying. I don't know what to do either, so I'm just inside.
Better get your doc to recommend a good shrink.
You really need to go to a doctor. Staying in your room is adding to the depression and anxiety.
