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.

If you haven't stared at a wall deciding whether to continue living or not - you have not lived. No trivialization here.
