Is refusing to live in an entire town because of trauma attached to that place valid, or not?
Yes, it is valid. A decade later, one of the boys who used to beat me up school recognised me on the street and gloated about how he'd "used to kick the shit out of you [me]", to quote his exact words. I was shaking with fear. As long as I lived there, I could come across him or any of the other boys who beat me up, and in two cases sexually assaulted me, at any time just going about my business. I'm merely autistic, without a complex personality disorder, and he still had that much adverse effect on me. Reader, I left town and refuse to go back.
What do you think this lass might have endured and how terrified do you think she might genuinely be? Consider how overrepresented mentally-ill women are as sexual assault victims?
