I've known an ADHD-Kid that was really suffering most from the typical self-consciousness-issues. The kid was in the boyscouts-group I used to run. I - ADHD myself - always had a pretty good connection to the kid, so we got to talk by the campfire one evening and the kid told me that what hurt them the most (kid was about 12 at the time) was that their parents always told them to see their ADHD as their super special superpower and as a boon. Yet, the kid was not at all able to see it that way (go figure) and thus felt even worse because they felt that they were so incompetent that they could not even use that superpower they got as such but only got negative effects on their life from it.

I never tried to insert myself into the upbringing of any of the children (that'd be super out of place), it was pretty hard for me to help the kid navigate this issue...
