Even if the world sucks, the logical, smart response would not be despair and depression, because that fixes nothing.
How logically do most people act, in your estimation? How logically would they act, if an unbearable depression descended upon them through looking at the shape of the world today? How many active genocides are taking place? How quickly will climate change destroy our way of life, and is there anything you, as an individual, can do to stop it? What about food and water insecurity being faced by millions of people? Millions of Americans, even? Lack of healthcare, the widening income gap between the 1% and everyone else? What can you logically do to address these global, ever worsening issues?
Perhaps the fact that you can't do anything about these very real issues can also be a source of depression? Especially when you're struggling just to keep your head above the metaphorical water?
One of the last vestiges of hope is a belief in karma. That the evil people perpetuating these evil things will one day face justice. But that's not true, is it? kissinger never faced consequences. Somehow I doubt trump or netenyahoo will either.
I imagine your answer is probably something along the lines of "focus on your immediate needs and community." Which boils down to, ignore these problems, because there's nothing you can do. Kinda like telling an employee aboard a star ship to tidy their working area as the main computer counts down the self-destruction sequence.
I, for one, cannot imagine that Sisyphus is happy.
