This is almost exactly the way I feel. I only connect with people in the context of my work, and that interaction with people in person has been taken away from me. I still have a job and work from home. So I am one of the lucky ones and I know it.
However, I hate working from home. My energy has always depended on interacting with people at work, and I've always had a real high wall between work and home.
I know I'm lucky. It doesn't help.
I'm so sorry for your issues with your neighbors. At least I don't have that, at least at the moment.
