This sounds like either bad mood or depression, depending on how long it has been going on.
My impression is that you're getting way in over your head on these issues when it's just your body failing to produce the right endorphins.
Yes, having successes can help to produce endorphins, but our bodies are dumbasses. Literally going outside when it's sunny is often more effective. Doing sports is often more effective.
Yes, this means struggling against it some more. Having depression is not easy. But I'm also saying that the solution might be much simpler than fixing the whole world. And you should not focus on fixing the whole world, you should focus on fixing your dumbass body.
