I've been dealing with a lot of the same. I isolate because that's how I'm most comfortable, but then there are times when I do start feeling desperately lonely and alone. I do chores every day to keep my apartment decently clean. And there's always laundry, dishes, and the routine stuff.
I was doing art work for some years, but all of a sudden I burned out on it, at least for now. I love being on PC. I play a few games online. I watch videos on youtube, also have taken classes from Udemy. I sometimes watch movies. I try to have a good book or 2 to read for a couple of hours each night.
Annnd...that's about it.
