Hello Dundermiffilin: Thank you for bringing your concern here to PC.

I believe this is your first post here on PC. Welcome to Psych Central.
I'm sorry you find yourself to be in such a difficult situation. You mentioned being barely able to concentrate to get anything done & avoiding people because you feel as though you're constantly being watched. You wondered if there are medications you could take that would help. There certainly are medications that could help with the things you're struggling with. However I'm not a mental health professional (most of us here on PC are not.) So I can't tell you what medications might be appropriate. That would be something that would have to be determined by your doctor or a psychiatrist. What medications they might recommend is going to depend on what they determine your mental health diagnosis to be. Here are links to 2 articles by our host Dr. John Grohol, Psy.D. 1 on anxiety disorders and 1 on social anxiety:

You also asked about programs that help with housing. Since I don't live where you live I can't really offer anything specific with regard to that. It also may depend on whether you live in a major metropolitan area or a small town or rural area. However, under any circumstances, what I would suggest is that you contact whatever state or county social services agencies are responsible for the area you live in.
You could also check out any not-for-profit organizations that provide services to the poor & / or the homeless. Realistically I know how tough a situation this can be. There are too many homeless people all across the U.S. And with the current pandemic situation this is only likely to get worse as time goes on. But I think, under any circumstances, it's important to try & keep trying.
I'm sorry I don't have anything more concrete to offer you. Perhaps there will yet be other PC members who will have more specific suggestions. I hope you find PC to be of benefit.
