Speaking as a young, single and lives in an apartment person. As an introvert I've often relied on being present among people to kind of substitute for my social life. With that not being present, it really puts focus on the presence or lack of social network. I'm actually grateful in a way that it has forced me to reach out to people in my network, that I otherwise wouldn't have..
I might be some kind of extreme introvert, because I don't miss people in my office at all. In fact it feels like a relief, for professional reasons I've had to be more outgoing that I'd like to and that feels extremely tiring after a while.
As much as your boss might want it, your coworkers don't have to be your friends if you don't want to. The greatest advantage of working remotely is that you can choose who you want to spend your working time, lunches, etc, with. Maybe it's just yourself.
