The superficial injury that your sister suffered about three inch above the eye does not have to do anything with the problem of personality disorder. This type of superficial injury does not lead to any kind of brain damage. Hence, please relax and ask your sister also to take it easy.
For the abnormal behaviour and personality disorder, it is very prudent to consult a psychiatrist.
