To tack onto this- for folks who can hyperfixate or are prone to pretty severe anxiety, it's also extremely damaging to say "you have to be dialed into the news at all times, no matter how terrible, no matter how powerless you individually are, or you're going to fall to The Propaganda"
Because for one- no, no you're not. But for two, one of the biggest, one of the most necessary means of controlling and living with that sort of anxiety or (speaking personally) dealing with post-traumatic stress is managing your exposure to things that can be upsetting, things that can drive that stress way up. If anxiety can render you wholly unable to function and you're exposing yourself to a machine made to keep you engaged 24/7 with it (and its advertising) by amplifying every Bad Thing it can find (which, sorry, no matter the source, this is how a lot of news works, it's still a business,) you're not going to 'bear witness,' you're going to drive yourself into an early and preventable grave, helping nobody, especially yourself.
"Focus on the things you can do in your immediate surroundings" isn't just advice, it's a survival mantra for people like me.
