Being a teenager is tough. And being a 'perfectionist' at this age is not weird at all. This is coming from a girl who is very similar to her age and who has had issues with cutting too. I didn't get the chance to go to therapy… but I'm pretty sure if I did. I would have seen how bad it was to be self harming and I would have had someone to talk too. I highly recommend seeing if she would like to go to therapy… But don't force her to go. It may make things worse… because teens are defiant. I don't think I would have gone to therapy then… because I didn't really know how to open up to my problems. And as much as I was willing to deny it… I NEEDED help. And so does she… Give her the love and support she needs. She may be trying to hide things from you but I did the same thing because deep down inside I wanted someone to go out of there way to care. Be that person.
