I am trying to find a movie about two sisters, one of them was spoiled and the other was neglected by her parents. The sisters were either twins or normal sisters. The mother hates the neglected one and sends her to mental hospital. The girl eventually meets someone over there, who shows her the way to escape.she escapes the hospital and tells her dad how her mother tricked her. She spoiled girl bullies her sister at high school and leaks her photos. Kindly, read the description and suggest movies names. I saw a short clip of this movie on facebook. It is based on a book series.
