I believe drugs are over prescribed. It seems that drugs are sometimes invented, and then a "problem" as well for the drug to treat. For example some people are shy. This is now known as "social anxiety disorder", and you can get meds for it. Along with a host of different "disorders". It seems the goal is to make us all more similar. Some people seem to be overly outgoing, no drugs for them?
I do lend some credence to society being sick, and wonder if perhaps the well adjusted ones aren't somehow abnormal. And yeah, at this point in my life I would be considered well adjusted.
