Rinpoche checked more for your daughter and said you should recite the Vajra Cutter Sutra. Try to recite it once each day.
You can also sponsor the recitation at Kopan Monastery, but not just one time, try to sponsor more. Your wife can also recite it, if she is willing to.
Rinpoche said it would be very good if all the course people at the Light of the Path retreat recite it one time for her. Maybe you can explain the difficulties and then people can recite the sutra and dedicate for her.
I have some incense for you to burn when it gets bad. (That means light the incense and sprinkle it on.) Rinpoche said there is another protection that she can wear if she is willing to.
