It does seem like a daily assault on our well being, doesn't it? But there is something that helps with this - read history broadly. It helps give you a deeper understanding of current events that lessens the impact of the current moment. And consider the quote "this too shall pass". It's attributed to Sufi poets about impermanence. If times are bad it gives you hope that those times will one day, eventually but certainly, be gone. If times are good it makes you relish the moment deeply and do what you can to make it last.
