Can someone help me find the name of this movie. It was a 90s film I think, either a lifetime/made for TV/ or actual theatre film. There were a family with a daughter and brother the girl was a teen and her brother was younger and the girl had a friend. Somebody did something that was really bad I forget what it was 'the movie was a physcological suspense" at the end it turns out the girl who's family was in it was the guilty one despite the film made it out to be like it was her friend who was probably the one who did it. The girl ends up raising a gun to her family and then ends up taking her own life. There was a scene earlier in the movie where she flips out at her younger brother for reading her diary which was a clue the she was hiding something. Can anyone clue me in on the film?
