Work hasn't left me in tears, but it is just a constant demoralizing drag. (I know, "so it's like... work?")

Nope, work shouldn't be inherently demoralizing imo. We spend all day at it. I'm sorry it's so sucky.

I also want to be at least somewhat informed about all the ways the US is deeply fucked

You could use wtfjht_feed it's a daily summary. Much more manageable than constant input.

And then I feel bad that it makes me feel as shitty as it does, because I know so many people who are being impacted in vastly worse ways.

Suffering is not a competition, all suffering sucks *hugs*
