I think in some way, taking an idea like that and treating it as fact was some sort of bizarre, twisted self-harm. internalizing & repeating it, making myself believe it, in order to punish myself. "you're worthless", "nobody loves you", "you're going to kill yourself by 30".
most of my life was filled with passive suicidal ideation, which is quite the weight to carry around. I didn't know how to deal with it, and didn't think I deserved to feel better. it sat in my mind, taking up space. it slowly grew and grew over the course of many years,
