What special interest do you have that you'd like to make a career of but are being held back because of required social interaction?
Your narration pretty much describes my history. Fortunately I write for a living; no people contact required.
Had past jobs, though, working around people. Never fit in. Never fit in ANYWHERE at anytime in my life.
In college, though, was a group of Born Again Christians who kind of took me in (I wasn't as enthusiastic about Christ like they were), but I found it interesting that they more easily tolerated my oddness, but I knew they probably fought internally quite hard to kindly put up with my info-dumps (I wouldn't be diagnosed autistic till many years later). But it wasn't true friendship with them; just the novelty of "Hey, a group who acts like they accept me!"
Lifelong difficulty fitting in, e.g., volleyball groups post-college.
Thank God I have editorial and proofreading skills, allowing work from home. Will never go back to a traditional job setting.
