That's not Codie wanting to fix your 14 year old child, that's MAMA! No more dysfunctional than if you found somebody cutting her and stomped the living snot out of them with a doc Martin.
You did good mama! My daughter was a cutter too. With therapy, she learned to express her considerable anxiety. She's now helping many girls in NA with the same issue. Her step mom was abusive and I didn't see the signs. She was afraid to talk and put on the fake smile. Just keep loving on her like you are!
