dear sir
i have gone through the history provided by you. after all these tests symptoms and signs are not co-relating. your child may not be having any major illness, hence you need not to worry. its better if you can consult CHILD
PSYCHIATRIST. because this is the age at which most of the children suffer the illness which your child is suffering. kindly behave friendly with your child. encourage her to overcome her problem but never show too much mercy. hope my answer is helpful to you
regards
