After reading most of the topic, I agree with the ones associating your problem with social situation more than skills. That being said, it seems a psychologist or a supporting partner or a good friend would help you much more than a degree.
A degree is nothing more than a piece of paper confirming your skills. Well, I don't have a degree in english, yet you understand me. You are getting the job done without a degree - good for you. Especially since it seems most of the schools won't really teach you much at this point.
Think of it like this: your coworkers may be the guitarists that finished music schools and after years of struggling, tears and being forced by their parents, and are probably able to play their guitars with a decent level of skill. That still doesn't mean you can't be a Slash that mastered the guitar while sitting on a toilet. Ask Slash if he cries all night because he doesn't have a music degree.
