I can't prove it but I really think her father abused her a lot. He was constantly "managing" her when she did streaming shit, she was constantly desperate for his attention, and she displays a lot of the same traits that children of abuse typically show when they first get out on their own. I 100% don't buy the bisexuality thing being legitimate either. It screams "cry for attention" in the same way her constantly harping on about addiction and recovery does.
I don't doubt she did psychotic and shit when she was constantly drunk, but it doesn't strike me as addictive personality that addicts have, but rather destructive coping mechanisms like you often see with trauma survivors.
