Yes I now know I had this, started late childhood and early teens. I know exactly which regular comments about my face triggered it, it's linked to very bad Kp. I also remember that blonde girls in adverts and cartoons, Barbie etc, were seen as the "better" type of girl. I didn't have blonde hair.
I don't have the other anxieties mentioned, eg ocd, but I was a very conscientious person.
I remember not being able to walk down a high st at university without pretending to want to try on some clothes so I could "check" my face in the mirror of a changing room. I wear make up as a control method.
I don't know why there aren't more links made to body dysmorphia and trans identities , especially the need to control how you look.
There's obviously cross overs to anorexia too which is more around anxiety and need for control.
Anxiety and resulting need for control are very human experiences but are definitely more common in people on the autistic spectrum.
