Exactly. Venting when life is rough is sometimes a good thing, but if it becomes the focus of most conversations and actions, it can even become something of an excuse: if you’re miserable, it’s a lot easier to sit around and be miserable (see: Eeyore) than it is to say, “okay, I don’t like this, so what am I going to do about it?” and go, well, do it: get out, start working on doctoral program applications to schools in areas with a higher percentage of young people, take a cooking class, begin a half-marathon training program, what-have-you.
I suspect that our highly electronic age also contributes to this phenomenon. Now you can spend all evening on Facebook “hanging out” with people without ever actually making human contact, and getting progressively more depressed because “everyone” else has a significant other/better job/more interesting hobby, or spend all night gaming with total strangers and having the most superficial interactions possible with strangers you’ll never meet.
(And I say that as someone who thoroughly enjoys spending an evening running video game raids and such from time to time, but who also limits raid nights to once or twice a week in order to avoid falling into that trap.)
