But also possibly..
I was the girl at school in the 80s who was shy, nervous, high achieving, loved routines, obsessive, wanted in a way to be in plays and productions but found the whole idea too anxiety-provoking.
Hated parties and social events. Always had friends though who thought I was funny and kind and invited me to lots of things. I would never host sleepovers or parties as they were too anxiety-provoking.
Extreme negative reaction to going to both primary and secondary school.
Primary I cried every day for weeks to the point my Mum wanted to pull me out. My Dad (it was a local school a few streets away from where we lived and we lived above the shop my parents ran) would torture himself walking down to the school at break-time hoping to see me playing and being broken-hearted watching me walking around on my own in my over-sized duffle coat. It got better for me eventually.
Secondary, was worse for me. I had 25 days sick in the 1st term and it was miles away from home and i cried most days. My Dad took me out for a walk one day and said he realised I hated it but I had to give it a chance and if it was still bad by Xmas, we'd look at alternatives. By Xmas I'd settled in enough and had some friends.
Decades on, I'm still the same. If I engage in those 'self-assesment ASC' things it will always tell me I'm highly likely to be Autistic.
I'm not Autistic. Never have been. I am an extreme introvert with an anxiety disorder in adulthood. That's it.
What's not helpful now, is lots of people jumping to say "ASC or ADHD or other ND when that isn't necessarily the case.
People have personalities, and likes, dislikes and preferences.
Considering ND, MH, trauma etc is helpful but we seem to be reaching a stage now where it's the default assumption.
And that's not always the case or helpful.
