When I was growing up I knew a boy who suddenly, around 12 years old, in an otherwise healthy-seeming family, began behaving badly - violence, drugs, flunking out of school, etc. Many years later, he told me the turning point: He was raped and felt he couldn't tell his parents (I don't know who assaulted him). Maybe a/the question to ask is not how the girl recovered, but why it started.
I know this branch in the thread is purely speculative - but it sounds awfully familiar to me as well.
Dated a woman in college who fits that profile in every including being sent off to firms like TFA - it was rooted in a decade of rape by her older brother. Her mother fell into that “we don’t talk about such things” type of profile and so it was left to fester despite being addressed.
