I'm sorry to hear that. Have you considered your school social rejection was independent of receiving a diagnosis?
No. The second I was diagnosed, my mum told literally everyone; the whole family, friends of family, and soon my whole class knew. I really didn't like having a label anyway, without everyone and their dog knowing about it. So whoever blabbed it out to my whole class might as well have said I have the bubonic plague, because kids started treating me differently. Also I treated myself differently too. I felt quite normal before the diagnosis, then afterwards I began to question my entire existence and thinking that everything people did was because I have Asperger's, and I didn't feel normal any more.
I remember one time when I was 9 I was playing with my dolls with my 5-year-old cousin, we were pretending the dolls were us and our mums, and I made 'my mum doll' yell at 'me doll' for being cheeky, and my cousin suddenly made her doll yell to my doll, "yeah, you have Asperger's syndrome!" It made me freeze, as it just felt weird hearing that from a 5-year-old (who is 100% neurotypical). I didn't react though, I just carried on playing with the dolls.
Like when my mum and dad split up and my mum kept asking my dad for child maintenance support for me, I used to think the child maintenance support was something to do with me having a "disability". Or one time when the teacher handed out sweets to the class, I was the only one who got a red lollypop, and I thought she had given me a red lollypop because I had Asperger's and had to be treated differently or something.
Oh - and I'm not even going to go into the meningitis vaccination saga I faced in 1999. I never felt so singled out in all my life.
