I'm sorry about what happened to you. That being said, I don't think your anecdote is representative of the typical result of mental health care. Surely we would have less school shootings and smaller prison populations if we ended the fear mongering and stigmas associated with mental health and had more routine psychological evaluations.
For the record, 2nd grade is, IMO, way too young to start any kind of stimulant. I don't have ADD, but I do know "ADD/ADHD denial" can be the gateway drug for thinking other mental health acronyms are bullshit too.
