The school will inform both parents.It kills when your child is self harming. There's a "What did I do so wrong as a parent that made my child turn to this instead of to me?" and "I'm a horrible parent everyone else will think that to so CPS will take my kids." I suggest going to a local clinic or make the appointment and ask your dad to take you to GP and tell him it's girl problems. Any lie you can use to get in.
