My daughter 12 years at 11 years matured, her periods r not regular and her behaviour is not normal always she gets angry very fast, if I say anything she gives nagetive answer,and very stubborn, lazy we r worried about her.

I think you should take her to a doctor. That is all the advice I can give you sorry. I am sure the doctor can help.

You really didn't ask a question. Take her to a doctor. Or a Therapist.
