I'm well aware there's a police brutality problem in the US, including brutality against protesters and the US sending Federal troops into cities.
I'm well aware that Biden is the Democrat nominee and there's nothing to be done about it, and that after however much hemming and hawing he's going to make Kamala Harris his VP, and there's not much to be done about that either. That there likely won't be Medicare For All, or a safety net for millions of unemployed people, or any other really popular and obvious change that needs to be needed.
I'm well aware that China, a world away, is trying to stamp out Uyghurs through apartheid and likely soon genocide.
Scrolling Facebook, Twitter, etc just reminds us of these terrible things that are constantly happening, that we have little control over day to day. And yes, we should volunteer, donate, protest, prepare to respond. But day to day, there's not much we can do to fix it. We're instead stressing ourselves to death over things we can't control, at least right now. Don't forget they're problems, help where you can, but don't spend your life hyperfixated on them.
