I'm worried for the world. All I've been thinking about is WW3 and this shit makes me want to vomit. I can't even smoke weed anymore without having a near panic attack. I feel unmotivated. I wake up and immediately just want to go back to bed. I'm not trying to spread fear but the Doomsday clock is 90 seconds till midnight, during the Cuban missile crisis, it was 7 minutes before midnight. Can we just have one day of fucking peace? Can everyone just stop for one day and enjoy one day of peace?
I grew up during the Cold War, I had zero expectation that I'd live to adulthood, and I'm still unconvinced the world after 2000 exists. The way to cope is nihilism and/or activism.
Nuclear war, global warming makes the Earth uninhabitable, new plagues wipe out everyone, AI poisons us or creates nanotech grey goo, fascists take over and gas everyone who isn't them, a dinosaur-killer meteor hits the Earth again, eventually the Sun expands and fries the planet. You personally are going to die, probably long before any of those.
So you can either say "fuck it" and do your usual stuff anyway, or get involved in trying to stop or delay one of the disasters. Have fun with it.
