Dang, I would've "fired" her, too! You did the right thing: you said no to abusive behavior. It doesn't matter what kind of title she justified it with, she sounds like a bully. SHE ought to be the one feeling bad, not you! Maybe you don't need a sponsor -- it sounds like that can become another sort of addiction. (Or maybe you just need a nicer person who is supportive, not a jerk.) Your old self might have put up with her nonsense, but the new you isn't. Kuddos!
