I think a lot of psychiatric drugs predispose people for lack of energy and concentration and other things that makes it weary to be around people, so yes I think isolation can be positive in this sense. Try to get out and about on good days and stay home on the bad ones.
I feel better until I don’t. I like to isolate, but I start to slide downhill if I go too long without interaction with others. I’m more comfortable isolating myself, but I have had to accept that some socializing is necessary, even if I have a distaste for it.
