I keep an old notebook where I copy down lines that feel like they put bandages on something. Mary Oliver’s 'Wild Geese' is always my first recommendation—'You do not have to be good. You do not have to walk on your knees for a hundred miles through the desert, repenting.' That permission to just be hurt, without the pressure to fix it immediately, was a revelation after my last breakup. It doesn’t rush you toward hope; it makes a space for you where you are, and that in itself becomes the hope.
Sometimes more traditional, structured verse helps, too, because the formal beauty can hold the chaos. I’d suggest looking at 'Love After Love' by Derek Walcott. 'The time will come when, with elation, you will greet yourself arriving at your own door.' It frames healing as a return to a self you’d forgotten, not as finding something new. I found a PDF of his collected poems online after a friend whispered that quote to me, and I must have read that one page fifty times. It sits in your chest differently than vague platitudes.
