I had chills reading this!!
"an infinite abyss"
^ Aaaaaaaah this phrase hits so hard!! Very new and very effective!!
Love the ending, will surely be nominating this tomorrow )

The title suggests, to me, a child wanting/ needing to hide. "Tiny pretty things fall like stars" this creates a beautiful image, and yet the word "fall" is unsettling, especially when effectively repeated in the next few words: "fall like tiny glass bones" I almost recoiled, waiting for the impact and certain fracture of something so fragile. Then, on its own "breaking" putting this word on its own increases its impact. Nicely done!
From this point the poem changes, like a new scene, or perspective. We move from the impact to damage to a place where sleep/peace is prevented. Eyes that won't allow sleep. I'm now thinking whose eyes? "Shattering my breathlessness" this is interesting. To me these words suggests an easing of breath, breaking a bad breathing pattern. Did you mean this, as the poem continues into a disoriented image of spinning shards and the word "carve". Maybe, using, "shattering my breath" could work?
This "accountability" being responsible for the previous pain, the nightmares somehow, but then the words "carve out" suggests, removing this responsibility. Add to this the fine imagery of surrender. Then the request to swap this responsibility of causing the pain, perhaps, to asking to not be hurt. This phrasing, for me, nicely bookends the poem. The suggestion of something fragile, like a child, being damaged, perhaps? The last few words, specifically, the word "sky" suggests a personal connection and so a poem that has far deeper meaning that anyone could figure.
Overall, I found I connected emotionally with many elements of poem, whilst others pleasantly intrigued me.
