She was born in the midwest to an extremely catholic family with a pushover dad, narcissistic mom, and golden child brother who favors his mom over anything else to the point of bullying his sister for being the "black sheep" (aka mentally ill (OCD/BPD), her entire family ostracizes her). She ends up snapping from the constant mental/emotional abuse and threatens her mom and brother when she's a teen, this leads her family to call the police and have her thrown in the psych ward where she meets Toby (who is a psychiatrist working there).
