So yeah, the USA isn't the world but if the place you live in is falling apart its understandable to shrink your worldview down to the that which affects you most or that you witness the most often.

1. Don't feel like you have to stare into the abyss all the time. This is just self harm. Its like habitually looking at entries on the old rotten.com website. Nothing good will come of it.

2. Do something, anything, that you can do alone. Plant some flowers, pick up trash in the neighborhood, read a manual about combat first aid or small engine repair, pick a country at random as far away from the USA as you can point to on a map and start learning about its history and culture.

3. Find somewhere to do something, anything, with other people. Internet book club, see if any local groups/orgs need help feeding the hungry or helping the unhoused, probably some groups not too far away that exist to support one minority group or another that could use some help in research or outreach.

Also, the world is a complicated place with lots of different actors. China is doing some pretty cool and good things. There's a lot of scary situations that probably will lead to positive change in Africa and South America right now.
