Well, in fairness your mother was more evil than mine. Mine was evil, but she was legit mentally ill. Your mother, okay sure mentally ill too, but sounds like a full blown narcissist. You're best away from that shit.
I know it's hard, but you're here. You're beautiful and talented. You're not feeding her now, so...you know. Fuck her. Sometimes mothers can't give what they don't have. Her treatment of you was all about her and nothing about you. You aren't wrong or disordered, as hard as it is to accept...you showed up. That's all you did . Fuck her.
