I channel that into anger, rather than hopelessness, but I absolutely get you, it's hard being unable to stop things from happening that you see a thousand miles away,, and being fix some of the easiest stuff to fix. Now with the political climate with one side of most governments leaning very fascist, and then what's going on economically, everything is harder and more frustrating, much more expensive. But that's why I choose anger over hopelessness, because fuck these assholes, I'm not going to let these bastards grind us down, and you shouldn't either.

My advice would be to try to force yourself to live in the moment more, stay informed, but find other outlets for your life, even if it's just trying some pot and hallucinogenics, and channel your hopelessness into something positive, something that helps, even if it's just something that helps you, also music, listening to it, or playing it if you can, I can't, but music is always very therapeutic. Books or audiobooks work pretty well too.

Good luck, I really hope you find a way to overcome your sense of hopelessness, I know it's not easy, but life never is.
