I attempt to live sort of like this too. My mother is beside herself with all of the wildfires in the world. In my opinion that is like stabbing your hand with a fork. I’m aware of lots of problems in the world, but I can’t do much if anything about them. So I let them go - I’m not going to injure myself over something I can’t control. Uncertainty is the same - worry and anger injure yourself, but changes nothing. Don’t subject yourself to needless pain. I just wish I could live by these words all the time, but it’s hard.
