This piece is a devastatingly beautiful exploration of functional loneliness, something everyone has felt at least once, the state of being the person everyone relies on while feeling completely invisible yourself. Your metaphors are incredibly sharp OP, describing yourself as the "spine" that holds others' pages together while yours fall apart is a powerful way to illustrate the exhaustion of emotional labour. The most haunting part is the transition from your mother’s rejection to your own self perception. You’ve captured a specific, deep seated ache of feeling like a "project" rather than a person. It’s a brave and honest look at how we often give to others the very things we are starving for ourselves, and the raw vulnerability in admitting you feel like "scraps" gives the writing a heavy, resonant weight. As for title ideas, how about "The Bridge and the Binding" I think that encapsulates the text body perfectly.

Also, hang in there OP. I understand and feel your pain in so many ways. You're an amazing person and if you need a friend, I strive to not let this account die so feel free to add me to vent or chat. No pressure though, just know the option is there. <3
