You either find a way to cope or live your life worrying about something ultimately out of your control. As long as I'm voting and spending my money thoughtfully then I believe I'm doing enough.
Food insecurity is something outside of most people's control, last I checked, humans can only cope without food for about a week before death sets in.
It must be so tiring pretending to care about every single issue of the world. You must be a real white savor. I hope all the struggling people can hang on long enough for you to come save them.
I have empathy for others while understanding that their situation is outside of my control. I do small things like vote and help where I can but beyond that there is no point in harming your mental wellbeing when you are not in a position to help.
