With the depression and not wanting to go out, for me what has worked the best is to force myself to go somewhere even if it's just the library so that I am not hiding alone in my room. Remember some of the best steps you can take are small ones that you can handle.
It also sounds like you need to find a way to relax, since the added anxiety is probably making your other issues worse. My advice is to try to remember some healthy ways of relaxation that have helped you in the past, for me reading is very relaxing.
I hope you are feeling better soon.
