I feel like it probably is. I'm guilty of- until very recently, being in the first group you described, sort of. At the same time there were many people- t and inpatient staff- that thought I had bp but didn't have time or resources to test me fully.

I agree with waiting till late teens to dx. Sure there are some kids who will legitimately be having symptoms, but it's better to teach them coping skills then label them and every other kid who has their ups and downs and force feed rx's.

Just my opinion.
