F/up from yelling at the kids

So the children told their teachers what their mother did yesterday. M is terrified that her mom is going to find out she told her teacher what happened. I told her to not worry because her mom will think it was me and The Husband that did it. I have also scheduled an appointment for M with Mary Kay, our WONDERFUL family counselor. She is AMAZING!!! I think the best part is that the children trust her 100%. They have no fear with her. How can a person hate themselves so much that they treat an inocent child so horribly?
