I second the suggestion to look for ASD-centric groups. There is much less pressure to act in neurotypical ways in these groups. It looks like you are looking for acceptance among people, and the best way to do that is to find others who have similar tendencies to you. Also, if you want to socialize with NTs, you will have to learn the social skills that they approve of, which can often take a lot of work and is something I don't recommend for everyone with ASD.
What are your interests? There has got to be people out there who care about the same things that you do.

Given a “tentative” diagnosis as a child as I needed services at school for what was later correctly discovered to be a major anxiety disorder.
This misdiagnosis caused me significant stress, which lessened upon finding out the truth about myself from my current and past long-term therapists - that I am an anxious and highly sensitive person but do not have an autism spectrum disorder.
My diagnoses - social anxiety disorder and obsessive-compulsive disorder.
I’m no longer involved with the ASD world.
