ok so I watched this movie in 2011 it was about a teenage girl who a group of teenagers brainwash into thinking she’s someone else so they can get revenge. They move her in with the teacher she got fired from school and make her think that’s her mom. She also lives next door to her real sister who’s in a wheelchair. I remember they wanted to kill her near a lake or river near the end but for some reason they don’t and they have two more movies.

A teen is hated by her highschool friends, family and a teacher she got fired. A group of teens from school hypnotized her into believing she was someone else and she was living with her teacher who she got fired. She slowly starts to realize she’s not who they are telling her she is. I think she may of did something to her sister I’m not sure I remember her being in a wheel chair. There is also a sequel. I can’t remember the name please help!
