While I am not proud of my prior misbehavior, I'm thankful that my parents had enough medical knowledge to refuse to put me on pills.
So while it's certainly important to keep an eye on pharma, it's also wildly irresponsible, unfair, and unscientific to claim "it's mostly made-up because I don't like the implication that a lot of people have a mental problem". Particularly disgusting is including the anecdote about the person who faked ADHD symptoms to get stimulants, then killed himself when his supply was cut off: prescription drug abuse/addiction is a serious issue, but one that is completely separate from the proper diagnosis of a medical condition.
There's rightfully been a backlash against the "better living through chemistry" postwar mindset that every problem should be medicated. But I think in this case it's ultimately less about medicating and more about fear of and unwillingness to address mental issues.
