This is the best advice I’ve adopted recently for exactly the same perception. Focus on your life, maybe do your best to have a positive impact on the things that worry you. Decrease your engagement with the news cycle - know what’s going on, but only as much as you can handle without it affecting your mental health.
Learn to trust that things will be ok, even if you’re not entirely convinced they will. It may not solve the problems, but your sanity matters too
