Same. Being undiagnosed autistic is horrifying in high school. I was chronically depressed and suicidal and everyone avoided me like the plague because I was weird as fuck and had no social skills. I did drop out at 17, then delivered mail for a few years, then after I got diagnosed and put on proper meds went and got my diploma in adult education at 24, which was super chill. Ironically I decided to become a teacher, in part because I want to contribute to making school a little less horrifying to kids like I was. And the 7 years of delay ended up being a huge benefit, because I can stand in front 25 13 year-olds confidently at 28, but I could never have done that at 21.
