This is why they say ignorance is bliss.
I put energy into hobbies and spend time doing things with people IRL whenever possible.
I don't plan on having kids but I've worked with them my whole life. I would recommend spending time with children and vicariously seeing the world through their eyes.
My last line of cope is thinking about how many problems we're facing have either always been a problem that we're still trying to solve, or a problem that inherently doesn't get solved until reality forces us. By framing fascism, climate change, bigotry, etc this way the problems seem less immediately existential. Like, it almost seems obvious that human beings would consume the planet unless the consequences of such forced us to change our ways.
