You mean, the poem is needed to bring the news that our worlds are crumbling at our feet?
(And one could continue by saying that by acknowledging this fact, we can in a way let go of that fact? As in a sort of liberation. If my world is crumbling, then there’s nothing else I need to do?)
I know, that sounds terrible and it is probably way off mark.

Maybe then, as in the sharing of our burdens? Your acknowledgement of your pain, makes me not feel as lonely in my pain.

The other option I can think about is the one of sharing as a distraction, but I don’t think entertainment is the purpose of poetry or communication. Like you said, if we want to be entertained, we should watch a soap opera. Nothing wrong with that.
