As a retired clinical psychologist, I can confirm this really is major depression you're describing. The fact that it is provoked or triggered by social trends does not affect the diagnosis. When the symptoms interfere with activities of daily living to that extent, psychiatric intervention is needed, ideally involving meds as well as psychotherapy.

That said, you're right to point out the epidemiological factors causing it to happen so much, especially since it is (as I have also observed) so much more common in men. To those I would add that men are not being taught essential tools for managing their emotions or relationships in the adult world.
