Agree 100% with overdiagnosis. There are hardly any children, these days, where the mum doesn't diagnose their child as having ADHD/autism or some other 'disorder' due to 'behavioural issues' and absolutely no introspection on whether or not these issues are caused by lack of experience in parenting, environmental etc.
It seems parents want the child to have the issue, have it medicated and then they can blame every single incidence of everything they don't understand on a 'disorder'.
The child, meanwhile, lives with the self imposed stigma of having something wrong with them, needing 'managed' with medication and forever having low attainment levels because of selfish, lazy, neurotic adults perpetuated by pharma.
If I seem angry about it, it's because I am. Just last week, my SIL with questionable parenting skills (favours her daughter over her son and has her own issues) suggested my nephew may have autism because he doesn't like to be bossed around and argues about rules. She then proceeds to send me a TikTok reel which seemingly confirmed her diagnosis. I had to talk her down without saying I thought she was the one with the issues so she didn't run out and try to get my nephew medicated so she didn't have to put any effort into parenting.
Further to that, adults are having themselves diagnosed because they think being conflict avoidant, or having lack of attention span, immediately qualifies them for a 'delayed diagnosis' instead of considering their own screen time, phone time and lack of social skills as a result of these things and how we're all so coddled and PC in society that we can hardly say anything without being accused of being confrontational. So, if someone says something that is misconstrued or even normal but novel to an individual, that person assumes they're 'neurodivergent' instead of just in need of social skills via exposure.
I'm exasperated. It is so draining because there really are individuals with legitimate neuro conditions and suddenly they can't get the help they need because the system is overloaded.
Autism.org confirms what I'm saying. There is literally less than 10% of people on earth with true autism and it goes on to discuss overdiagnosis etc.
Edited because I misunderstood your post, initially, but hopefully this will explain why people are fed up with the 'narrative' and it's not a go at you, so please don't take it that way, but hopefully it makes you feel a little better and not singled out when you understand where this is all coming from.
