What your describing is probably something most of us can relate to, I'd surmise. I have tried my very best, not knowing I was "neurospicy" and an autist, for most of my life, but, the "Uncanny Valley" thing, I think, still persists, no matter how hard we try. We are just Oddites.
Certainly I know that there are people who might think they like me, but, from experience, I can't keep them impressed, given time, because I just don't have the amount of social energy needed to keep up friendships, and I'm not willing (or, most likely, capable) of conforming, to the standards, required of the social (unspoken) rules of the quote unquote neurotypical world.
Worse than being alone, I have found, is being surrounded by people who act like they despise you and are only using you. THAT is lonelier than alone IME.
I used to get time jamming and admittedly, there is something magical about a good jam session. I just can't maintain social opportunities for myself, for the reasons above. So solo it's gonna have to be. I'm guessing.
