I don’t know, a lot of the symptoms are pretty dead on for me. What do you think is a good example where the diagnostic criteria are wrong/incomplete?

There's the whole issue of girls being underdiagnosed because they don't neatly fit the stereotype of autistic boys. There's also the tendency to underdiagnose NTs in general who have found coping mechanisms to mask the symptoms. People who put in twice as much effort as other students just to get by may not get accommodations because their grades are too good for box-tickers.

Also, if they're not qualified to give a diagnosis, they might be hesitant to say anything (similar to how x-ray techs won't tell you anything about how the x-rays look). Or they might just assume you already know. Or worried you might think they're insulting you if they suggest you're autistic.

I feel like I should have had a stronger reaction to like puberty, ya know?

I don't think I really had any sort of reaction. But I wonder if I might have already been dealing with chronic dissociation even back then. So it wasn't something I really considered my body anyways and even if I did, I didn't think there was anything that could be done about it. But there's no requirement to have any sort of reaction like that.
