text: i'v been hit by a car and i'm 12. can u help me? i'm 12. been hit by a car. nurse said i have to wear a cast. coz its a hair line fracture. but the big problem iz that i can't sleep coz of the cast. wat should i do? get your mates to write something nice on it and read it at bedtime. you'll soon get used to it being on you and if you are anything like rooney, it'll soon be healed! good luck and keep away from the roads!
