I think I am a vampire?

A girl, Noel and her mother live together in a small city near London. Her mother is an alcoholic. Noel is 17 but graduated high school last year. Since then she is trying to save money to move out. Her brother Jackson is dead, he died when he was 5 before Noel was born,or at least that's what she thinks. Noel had an accident after a party BUT what happens next?

Blood is the answer
