Your word choice in this is so unflinchingly honest and packs a punch. I keep going back to "catacombs of existence". I felt the agony, the question of why is there more suffering, when you are already going through enough? And that's exactly what our mind can convince us of, that it's too much. Some really emotive verbs and images in this. Also, "Prune away the fragmented pieces that leave me yearning for her." showed me the pain in loving someone and possibly losing them? The ability in our hearts, the openness, to love.... and having that tainted, having that part of us all the more vulnerable.
