I hear you, and I'm down to almost nothing myself.
Not that this solves anything but:
Sometimes it helps me to think of it like we're characters in an epic story, or historic figures to future generations. This could be part of the reason Q said things like 'history books' and 'watching a movie' and '40K feet'- to encourage us to stand back and look at things from a bigger perspective, detached from our personal frustrations and suffering.
Speaking of movies, this scene in LOTR is inspiring to me and makes the same kind of point-
Frodo: I can’t do this, Sam.
Sam: I know. It’s all wrong. By rights we shouldn’t even be here. But we are. It’s like in the great stories, Mr. Frodo. The ones that really mattered. Full of darkness and danger they were. And sometimes you didn’t want to know the end. Because how could the end be happy? How could the world go back to the way it was when so much bad had happened.
But in the end, it’s only a passing thing, this shadow. Even darkness must pass. A new day will come. And when the sun shines it will shine out the clearer. Those were the stories that stayed with you. That meant something. Even if you were too small to understand why. But I think, Mr. Frodo, I do understand. I know now. Folk in those stories had lots of chances of turning back only they didn’t. Because they were holding on to something.
Frodo: What are we holding on to, Sam?
Sam: That there’s some good in this world, Mr. Frodo. And it’s worth fighting for.
