bpd culture is butterfly on your right shoulder by norip.
specifically the lyrics, "please hold my distorted body close to you. only you will fill it up. / isn't that right? see, you understand it, too! you've already crossed the boundary. / i have so much regret that i could die, but i also conjure up just as much pleasure. / please stop me as i'm going out of control, and give me peace and comfort."

i have so much regret that i could die, but i also conjure up just as much pleasure / please stop me as i’m going out of control, and give me peace and comfort / what has begun to dissolve into my wound? is it love, or…? ah…
