Psych meds for something like schizophrenia or acute psychosis are very different than for things like ADD, Depression, etc. Additionally, it is objectively true that these disorders are overdiagnosed (there are many studies backing this up).

Some psychiatric issues fit much more closely with the disease model of medicine (like psychosis), and others are in a huge gray area.

Most of psychiatric work is in that gray area and does a poor job of it.

Even a former DSM chair thinks so. I highly recommend reading "saving normal" for more info.
