I felt the same a year ago when I realized I might share some traits described by autistic people. It was first a relief, a convenient explanation to most things I struggle with, and some “strange” traits of mine.
However, a diagnosis is very difficult to get in my country (years of waiting, not even sure I would get it one day). I decided not to do it because I don’t feel it would change anything beyond the validation. I don’t consider myself as truly autistic since I have no diagnosis, but I keep it in mind when I encounter difficulties, and it helped me a few times.
