I certainly agree with you that this world is--as a whole, that is--crazy, incoherent, as if [it's] a hormone-riddled teenager high on hormones, at the dizzying heights of angst. But that teenager even sometimes goes out to have a chill drink somewhere, but that's beside the point.
I think in a way, everyone who lives--yes, including the non-suicidal--have themselves a way of hiding from the insanity of the whole world, from time to time. Every little coffee-shop chat like a pocket from the cold in the whole of the outside. Sometimes we go out from our sanctuary and find novel peaces along with novel insanities.
My way of dealing with how crazy the world as a whole, is sometimes to remember that you're not the only one who recognizes is, and feels appalled by it. There is good reason why people don't talk & think [of] politics 24/7, the world is a chaotic and hard to deal with place, so we save ourselves and take breaks.
Know that the world was not made for anyone in particular; so even if it's not for anyone, that also means it's for everyone as well, whether that be a good or bad thing. I say that it's possible for us to make places there[,] for ourselves, despite all the alienation and confusion throughout here and there--to make sanctuary from the rubble, and know people who are worth knowing. My words put forth.
