Nanny obsessed with little girl and man
I think she hates her mother and for some reason she starts working as a nanny. I know she keeps a diary where she writes about her 'prince charming'. Then she becomes obsessed with a little girl she's taking care of and one night she meets a man and she forces him to fall in love with her.. He refuses and so she kills him. In the end, I remember she jumped off the rooftop chasing a ball that had fallen off the building. I know my description is kind of messy but if you've seen it, you'll know what I'm talking about. PLEASE, I need the name of that movie!
