Is mental illness a myth?

It's just categories of behaviour, which a group of doctors have decided, by their subjective whims, are "illnesses". Can behaviour really be an illness? Is being in love an illness? Should we drug people who are in love?

And do mental illness drugs really help patients? Or are they just intended to control patients? The first antipsychotic, Thorazine (chlorpromazine), was advertised by the fact that it "quickly puts an end to his violent outburst". Pretty clearly, if the drug is being thought about in those terms, then it is only intended to be to the benefit of OTHERS, not the patient themselves.

Emotional distress is of course real. But should we label it as an "illness"? Emotional distress is not an "illness" in the way of other illnesses, which are usually specific, identifiable, physical dysfunctions of the human body.

I contend that mental illness is a myth, designed to control "troublesome" people. These people might have genuine emotional problems, perhaps brought about by abuse and other problems, but society doesn't care about that - it just wants to control these people so they don't act out.
