Friend I don't know where you call home but most major metropolitan areas are filled with non-stop ads and minimalist architecture. Minimalism is the cheapest/quickest way to build upwards, and the non-stop ads in your face are intended to wear you down into buying shit you don't need or even necessarily want.

Also there's more to NYC than just Manhattan. I'd urge you to check out any part of the other boroughs and you'll probably be pleasantly surprised by how "human" everything can be (unless you're in like, Downtown Brooklyn or another shopping/government building district).

Buck up, the world ain't over yet. If you wanna feel better, buy less shit and go for a walk through the park. Forest Park is dope, even little Highland Park is cute as two boots.
