++ if this turns into self-harming behavior (I cut myself and I left a scar and NOBODY CAN STOP ME. I can make myself ugly so nobody wants to fuck me again or I can make myself pretty with all these intricate designs I don't give a FUCK if they bleed or hurt Steve).
Bucky gets kind of cocky about his self-harm. "I get to be the one who hurts me now! I decide when and where and how! I can cut myself, or burn myself, or smash my hand with something and it's all up to me how far to go. No one else gets to hurt me, just me." And on and on like that, internally or out loud. Steve is going crazy with it and it takes him forever to understand that whole reason Bucky wants to be the one to hurt himself is that he genuinely cannot comprehend the possibility of no one hurting him.
Re: Bucky aggressively owning his bodily autonomy (eating disorder and/or self harm possibly)
