I'm a bit dual about this thing. I see it around social media and in people talking.
I got diagnosed almost two years ago, and it has been a relief in a way because it finally explained a lot of the struggles I had, helped being less blameful about myself and learn physiological keys around how I am and why.
At the same time, I really don't think it would have helped me knowing this much earlier in my childhood, and sometimes the tentation to use this as an "excuse" is strong like described in the article.
I wouldn't wish an earlier diagnostic to my kids, and try to approach things with an empathic approach instead.
