Honestly I have no idea what to say to make anything better. What she did and continues to do is sick and disgusting not only as a human being but especially as a mother. Your daughter shouldn't be in a situation like that. Have you tried to talk to the police or protective services about it? Using an innocent child as leverage to get what you want is so disgusting to me. Is there anyone who could attest for her behavior? She sounds narcissistic, manipulative and frankly, insane. I really hope you talk to someone who can save your daughter from her. I don't even want to think of the things she is doing or saying in front of her.
