Touch grass.
No, seriously. I know most people use this as an insult but in this case I think there is a lot of benefit to re-balancing your time and getting offline. As a general rule, the further away the turmoil, the less impact you can actually have on its outcome. So why build up anxiety over something that is limited to your ability to control? Take that anxiety and put it in your immediate world. Your home, your physical health (diet, meditation, sleep, exercise). Get new hobbies like learning a musical instrument, go out on hikes. Find locla community.
I get one may not wish to bury their head in the sand but you need to strike a balance. If you still want to get active, then go to protests and join local political communities that align with your beliefs. It helps a lot. Focus on what you have more agency over and you'll feel better. Things like diet and exercise and getting out into nature all directly reduce anxiety and improve mood; that's a fact.
