I'm sorry you feel so lonely, and I can identify with that. Even though I have a wife and children and a lot of shallow acquaintances, I don't have any really close friends. Online satisfies that somewhat but I still feel lonely even surrounded by people who love or like me. It's really good that you can identify that loneliness is fueling PMO for you, and neediness is fueling loneliness, and unworthiness is fueling neediness. So you're tracing it back to its source. So what fuels the sense of unworthiness? Can you go back to the original source and work through that? Something from childhood, maybe. Keep at it, you're getting down to the source of the problem. That means success is within reach, maybe more so than ever before.
