I'm not criticizing your preferences at all, but I think it's really strange for you to describe them as loneliness. I would say you work alone, but you're not lonely, because you have a bunch of other social connections in your life that for some people are replaced by coworkers. If anything, your comment reflects a kind of strange default on HN where work consumes so much of your life that coworkers are your "friends" and working alone is the same as being lonely.
