Normal, but there will be times it is worse than others.. Track her periods and you will probably find a pattern. Her mind is racing in a lot of different ways.
Is she about to be a freshman in high school? There is a huge adjustment. She will once again be low man on the totem pole so she could be worried about that. Also her grades will now really count and I bet at school they are signing up for classes and talking about taking school more seriously.
That being said, you need to remind her that her tone is not appreciated. If she wants to be treated like a mature teen she needs to act and speak like one. No eye rolling and no slamming doors. Remind her that her cell phone, TV and social life depend on her continued good behavior and attitude.
What is really interesting is that she will be like this and another moment a puddle crying, so just be prepared. I used to tell our daughter, "maybe you need a break." "Why don;t you go have some quiet time in your room. I will bring you some tea." And then I would make up a little tea tray with a little treat and leave it for her in her room. She just needed to find some coping skills. .
Carl Pickard says this is Gods way of helping you let her leave for college when she graduates. You will be ready to close the door behind her.. Hee, hee,,
I am sending you strength. It does not have to be bad, as long as she knows she is free to tell you anything and you will not freak out. Try to remember what you feel like with PMS x 100....
