Sax - I guess one cannot know what you are feeling unless they've actually gone through such a crisis. It appears God is answering our prayers and your daughter is recovering. It will more than likely be a slow process but from what you are updating - the prognosis appears promising. I guess she isn't out of the wood yet but improving. Thank God.
As for the boy - God does say to turn the other cheek. And at this point, if I were you, I would focus all my love and attention towards your daughter as I am sure you are. Let the law deal with the boy's fate.
My prayers will continue for you my friend.
