I remember watching a movie like 4 years ago but I can't remember exactly all of it. I know that it's about 2 teen girls aand they're best friends. Im pretty sure one of them is like a partier and the other cuts herself or something. I think there was something in the movie about how the one that likes to party is hooking up with the others dad or something. I can't exactly remember. Well the one cuts herself and the other sneaks in her room after a party and falls asleep in bed with her. And in the morning the girls sleeve is all bloody from cutting. This is really going to bother me because I can't think of the name of it. I keep remembering all these bits and pieces of it but the name just won't come to mind. I looked up Thirteen, but I don't think that's it
