Is it sudden. Behaviour? Definitely not, chek your parenting styles? What environment she is breathing ? does counseling required for parents? R u open to introspect as a couple

I would suggest you  both to consult a psychologist at first as parents. Then,  if required,  you can take her to a counselor.

Hi I can understand your emotions towards your daughter, definitely there should be some reason to her behavior. Either it is problem with parenting, or has she observed any similar behavior outside, work out on what all she had given exposure. Please observe , introspect yourself and discuss with your partner. Also now its the age of growth spurt, due to harmonal change also child can behave rudely. but don't decide on anything, Please consult any psychologist for better assessment and also even your family doctor can also help you. take care stay positive.
