To all the “don’t see the point” parents - if your children are at/near teenage years, why not involve them in the conversation and make a decision with them? It’s their life after all. The path of “functions or excels at school, all goes to shit at uni / the workplace” is a very well trodden one for ND folk.
I sought out diagnosis as an adult after feeling frankly odd or malfunctioning for most of my life, and usually taking it out on myself. My parents, school, work colleagues, friends, acquaintances would all tell you that I am lovely, smart, able etc - because I hid how I felt and worked 12 hours where others worked 8, to cover how inadequate I felt and how long things took to do. Oh, and self harmed on a massive scale. Including at home, as a teen. Always in places on my body where others wouldn’t see. I was in my late 30s when I sought out diagnosis. That’s over 30 years of feeling dumb, less than, malfunctioning, panicky, stressed, tripping over basic tasks. My parents didn’t and don’t have any idea.
I wish someone at home or school would have taken me aside and pointed out that I was good at a,b,c but seemed to battle with x,y,z, and let me know that it was ok and there were strategies we could try to help, let alone medication. That would have been very unlikely in my Commonwealth school in the 1990s, but hearing people say the same about their kids in the UK in 2024 is frankly heartbreaking.
