This is no way disregards the difficulty of living with an actually severe case of ADHD but is not what most of these people are dealing with.
EDIT: many seem to have misunderstood what I mean by this. I’m not saying these people are only claiming to have ADHD to use it as an excuse. What I mean, is that they may very well do have, and they’re using it as an excuse. Mostly to themselves.
I feel like we’re saying the same thing. Your argument (and mine) is that it’s hard for people to understand ADHD unless they have it. For this reason, people like me should keep their mouth shut about it, and if this weren’t an “unpopular opinion” thread I normally would. But for the same reason, I feel that people who haven’t had a proper diagnosis should be cautious about assuming that they do have ADHD, because maybe they don’t understand it either. If I didn’t follow my own advice, I might join the self-diagnosed crowd and start sharing personal coping strategies, and if it turns out I don’t have ADHD, those comments could be ignorant, offensive, or even harmful.
