Take it a little easy on that.

Unless you have adults that actively ignored or knew you had ADHD and refused to deal with it you’ve got to cut people a little slack. There’s centuries of raising kids where people forced them to conform, for good or ill. Centuries where adhd was not recognized. Centuries of sweeping mental differences under the rug. They just didn’t know.

We’re barely starting to acknowledge and accept mental health and non-normative brain wiring today, and there are still huge numbers of people that refuse to accept it, want to force conformity, or have some BS clickbait “treatment” for it.

My family is late diagnosis. It really hurt my other half because her parents knew but did nothing. She felt like years of her life were wasted because she never could stick with things that would have advanced her life in positive ways. I was an “inattentive” type that was essentially unrecognized because I wasn’t hyper. No fault of my parents because it wasn’t a thing to look for 40 odd years ago. Now I fit the diagnosis to a T. Even one of our own kids had issues that took us years to figure out even after suspicions on our part. Took the kid to local specialists and they’re all “Nah, normal but difficult kid.” Years more go by with lots of problems and we’re fed up, pay a fortune out of pocket (because insurance doesn’t cover mental treatment if it isn’t a problem) to a legit children’s specialist facility in a metro area and within a week we had a proper diagnosis, things have improved with the kid and our relationship with the kid drastically over the intervening years. Point being that, even though we tried to get a diagnosis it didn’t work, and we had to go out of our way, even if we were unsure of the issue, and spend a lot of money to figure it out. Not everyone has that kind of time, money, or stamina to sort out a difficult kid after already being told the kid is “normal”.

Sorry, WoT response, just offering a perspective.
