I would personally disagree with your "medications are not specifically harmful in a misdiagnosed case." I'm not encouraging people to avoid seeking whatever help they see fit, but rather to not whitewash over the very tractable impact it had on a rather dark year or two of my childhood, and the lasting aftereffects. I honestly don't want to start a heated debate about whether or not to medicate, moreso call out to others who had a similar negative outcome that they're not alone and that it's not impossible to develop healthy coping mechanisms without pills.

Depression, anxiety are co-morbid with ADHD/ADD as well.
