Our per-capita SSRI consumption is lower than more than a few EU countries'.
Also sadness is a natural and ok state of being. Being a gronked out happy zombie is unnatural and should be suspect.
What percentage of the US population that finds themselves in need of an SSRI or similar medication can afford to obtain and fill such a prescription as compared with citizens of EU countries that enjoy universal healthcare?
One should not trivialise depression. It is a lot different than just a feeling.
I've suffered from and been successfully treated for depression. I would describe it more as an addiction to feeling low than anything.
I suspect that in the EU there can very well have been a lot of overprescription of SSRI for conditions other than depression, however. Many times, people are just melancholy because of external life factors, and no drug could improve those.
