The book was about this girl who was telling the story on how she ended up in a place for girls with mental illnesses. The girl loved acting and stuff, and her mom always pushed her. She went to this boarding school and she stopped eating and fell for this gut who was way older them her. She got the lead in the play (Romeo and Juliette) and she started going out with/havering sex with the older guy. Then her and this guy made a plan to fake the girls kidnapping to get ransom money so they could run away together. The guy left her tied up in a ditch and she had to escape herself after a really long time. The twist was the while time she was hallucinating and none of that stuff actually happened. She tied herself up and stuff. The guy she claimed to be having sex with thought she was a crazy stalker. Him and his friends had nicknamed her "tinkerbell". That's all I can remember. Oh, I think the girl was 15. And she actually didn't get the lead in the play or anything.
