I don't argue with my diagnosis (in high school), but I disagree very much with the immediate decision to medicate. I felt very strongly at the time that the whole point was to sell medicine to my parents (Vyvance in my case).

It was just, "oh, his GPA's low? Seems like he can't focus? Here are some amphetamines, have a nice day!", with zero follow up about whether the medication was doing its job (didn't matter -- I never took it anyway).
