My communication issues means that I'm disabled.

I'm 26 working in a factory again as I search for employment with my economics degree. I just figured that I've always failed at life because I'm disabled. I couldn't make friends in highschool and I was ostracized and bullied. I couldn't make a friend in my graduate cohort and failed because of it. I can't talk effectively and I'm just a disabled guy overall. I don't have friends, I'm going back into depression. I just hate myself and my life honestly.
