Sorry to hear about your daughter. I am afraid I have not had the chance to meet her yet, as I am new to this forum, but I still wish to say that I hope she makes a recovery.
Not knowing the type of injury she has all I can really do is offer a quick scripture that I myself find comforting in times of distress, comes from rev. 21: 3-4.
"With that I heard a loud voice from the throne say: ?Look! The tent of God is with mankind, and he will reside with them, and they will be his people. And God himself will be with them. 4 And he will wipe out every tear from their eyes, and death will be no more, neither will mourning nor outcry nor pain be anymore. The former things have passed away.?
It talks about a time, hopefully very soon, in the future when we don't have to watch our loved ones get hurt. In the mean time I wish you and your family well.
