I believe those types of problems can be mitigated or even solved by changing your perspective. Example, I can’t get revenge on those people who wronged me. But I can forgive them. And through that, I no longer care. It is in the past, and like children who have stolen a cookie from my jar, I have to forgive them. And so I’m released from my anger.

I’m not sure what the solutions to those other problems are, but I think there would be solutions of a similar vein.
