Hey, good luck. The hard thing about recommending hobbies to strangers is that one don't know them so the only chance to guess is to project what I like. Moreover your issue is not lack of hobby, but being alone in the house due to logistic reasons.

When I was lonely and isolated (less then you), arguing on the Internet helped. It is not same as real communication and friends, but it more then nothing. Keeps you from loosing it entirely. Writing is communication too, altrough less effective.

Another weird thing was that when I finely had chance to communicate, it was tiring because I basically forgot how to do it. If that happens to you too, that is ok and normal. Don't get discouraged when talk won't go smoothy (as I did).

I wish you good luck, that something around you shows up.
