Her family is clearly dysfunctional (overbearing mother, enabling father, religious fanatic sister), so it makes perfect sense that she would be one of the goth kids in high school for attention, and one of those promiscuous women that sleep around and get pregnant after high school. It’s all about appearing special and cool because these people don’t know who they are, have the capabilities to love anyone, or have anything going on in their lives to begin with. Obviously no one can assess on TV but her persona screams BDP to me. Attention seeking. Unstable relationships. Never happy with what they have. Always pick fights. Emotionally unstable. Not accountable for their behaviors. Paranoia.
