Re: my friend,
First of all I have a "friend" called Abigial who always cuts and I used to help her until she had made me take her to hospital too many times!
But i can see you would like to help your friend so I would suggest attempting to cover them up You could use 3/4 length shorts so that they would cover most of her legs. Or couldn't she get her parents to write a note to the teacher to explain the situation and see if she would be allowed to where trousers during her PE lesson I'm sure the teacher would understand. If her parents don't know that she cuts than go straight up to them and tell them! or give them a call what-ever you have to tell them ok?
Love me for what I am hate me for what I am not
