I'm autistic. I'm also AFAB (Assigned Female At Birth). I was diagnosed with ADD as a kid. Which in the 1990s was still really rare for girls. Finding out that I'm Autistic was a relief. It gave me a reason for why I would have meltdowns over stuff that was seemingly not that big of a deal. It explains why I hate crowds. It explains why I have trouble with sarcasm and humor.
Also, most Autists prefer "Identity-first" (In other words: "Autistic person") language over "Person-first" ("Person with Autism") language. I know y'all aren't doing PFL to be malicious, just wanted to point that out for future reference.
some not-so-nice truths under the spoiler...

"Functioning" labels are ableist. "Asperger's" is also ableist and was literally named after a nazi who would send the "lower-functioning" Autistic children to be killed during WWII.
