As some of the other ladies have said, there is obviously some underlying issue causing your daughters behaviour. She's far too old to behaving this way out of the blue, "just because."
Best case scenario, due to the family schedule she's not getting enough attention from you & is left to her own devices too often. This can easily be fixed with some schedule changes & more family/one-on-one time.
Worst case scenario someone has hurt and/or upset her. This will most likely need to be discovered & treated by a professional if she won't readily tell you.
My suggestion is to first talk to her & ask her, "Are you alright? Is there something going on in your life you'd like to tell me about? Why do you think you've been acting out of character?" etc.
I wish you both the best of luck & hope nothing too serious is going on.
