Same. I believe I've suffered from autistic burnout for roughly the last year. I was pushing myself to be social, for my wife and other reasons. That led to me finally getting diagnosed.

Almost all of the autism resources I have found say something along the lines of "Autistic people actually love to be social with other people! It's just difficult because kfnthr double-empathy problem. Try making friends with autistic people". The psychologist, therapist, books, articles, everything. It all felt... Weird.

Then I talked to my older sister who was diagnosed almost a decade ago. She realized a while ago that socialization is just bad for her, so she stopped doing it and has been much happier and healthier ever since.
