My wife struggled with this one for years. She's a lot more caring & empathetic than I am and all the fucked up shit that goes on every day in our world was getting to her since she couldn't do a damn thing about it. Knowing that all this shit was happening and that she was also powerless to do a damn thing about it ate away at her.
Friend of ours had some great advice which helped her a lot. We need to adjust our circle of concern to better match our circle of influence, focus on the things we can do to make our little place in the world a bit better and don't get bent out of shape on the things we have no influence over. We all have the influence & ability to make tangible improvements in our immediate surroundings, and maybe even on a larger scale. We can't stop climate change but she did get a bunch of land designated as protected green space in various city planning meetings, thanks to her efforts it's now written into the 50 & 100 year plans for our city.
