Sol, I think you are right to do something about this, no more giving her time. Her pattern is to blow, make nice and then blow all over again. That is crazy making and dangerous. I'm not sure it's MC she most needs right now versus personal C and maybe medication. Yet, obviously, the stress of what's been happening in your M has had a huge impact on her behaviour. So, I guess, any form of help may be appropriate, anything to "do something different"!Has she heard of anger management classes? They could be helpful too. Bottom line is that you and your D cannot continue to live in a violent situation. It is not OK to do so and she needs to hear this. So do what you have to do, Sol. I'll be thinking of you.
