When I'm at home, I'm miserable and lonely, because I know I won't meet anyone at home.

When I force myself to go out, I'm miserable and lonely, because I'm alone and am unable to connect to someone when I'm by myself.

When I go out with friends, I feel miserable, because I know they will all go one with their lives after the night is done, and I go back to my miserable and lonely existance.

How do I get out of this cycle? Therapy doesn't seem to work, staying in doesn't work, going out doesn't work. I'm at the end of my rope.
