If you have such a recollection, how about researching it and providing evidence if it's genuinely the case, rather than putting out the vague but possibly unfounded suggestion?
Re your original reference to a 'study' involving NINE patients with no controls, it's just laughable.
No one would take it seriously. (I appreciate that you weren't doing so either.)
It has long been my concern that there is a growing tendency to medicalise/pathologise ordinary human emotions, viz sadness in response to an unhappy event, depression when suffering a debilitating illness, grief following the death or other loss of someone loved. Such emotional responses are normal, are part of the ups and downs of just living, and shouldn't - unless continuing to pathological levels - be considered problems to be treated.
Rather, I'd say that such emotional responses are a reassuring indication that someone is 'normal'.
I'm really alarmed at the spread of antidepressants in really young people and in the broader population at the slightest hint of anything less than glorious happiness. And the increasing use of potent stimulant medication for hyperactive children, even in infants, is worrying. Then the apparent intolerance of people to just ride out a period of insomnia, before swallowing potent hypnotics.
As you suggest, we seem to be getting ever closer to that expectation that there's a pill for everything.
