“You lucky you only had one family to fuck you over. I was in foster care and got to be fucked over by a bunch of different families.” Being abused by the people who were supposed to rescue them was the ultimate destruction of trust, so they fled, running away either literally or mentally. Therapists call this “dissociation.” On the street they call it being fucked over, and one solution to being fucked over is taking drugs, mostly heroin.
