If you had easier time when you were enrolled in school, then why not get yourself on a similar situation again? You can do the same now. Such as enrolling in college or take few classes here and there or at least get a job. You'd be surrounded by people and maybe some people would click. Staying home isn't going to get you far.

As about diagnosis. You need to see a psychiatrist. No psychiatrist would tell you that staying in bed for 2 months is perfectly fine. It's not. Hence you need a diagnosis and perhaps serious treatment. But you can't demand total strangers on the internet diagnose you. That's not how it works.
