I am so sorry to hear this. It's crazy when we have a normal life with our husbands but our kids make us crazy with their lifestyles.
Is it possible that your daughter is still using? Something doesn't seem right. I believe if she were sober she would not be treating you this way and that she would be making better decisions.
I have no advice except to take care of yourself. I am sure you already know this but sometimes we need to repeat it to ourselves and really take action too.
Prayers and hugs that you get some peace this Christmas.
