I don't disagree with a single word you said. But having perspective and leaving time to be human is not burying your head in the sand.

The last things I tried to say was that taking action is one thing you can do to mitigate your sense of helplessness. People who help others or try to make the world a better place often end up in a better mental space. It has the added benefit of working against all of the bad shit that is happening. Pick something, anything you care about, and try to make a difference. Even if you only make a tiny difference, if a thousand other people go out there and make the same tiny difference, suddenly you've moved the needle. In my experience, despair is nearly always coupled with paralyzed inaction.
