Santa should bring a replacement book! Sounds like your DD has the typical emotional intensity that some gifted kids have -- as well as the perfectionism ("WHY did I cut up my book???") I wouldn't worry about it.
I hear that gifted girls especially fret over their mistakes. Obviously as parents we have to teach them that they will make mistakes, and they need to learn to try again, or look for new ways to solve a problem.
Try telling that to my DD8 who is already at an early intermediate stage in her piano lessons! She expects everything to be easy; well, music can be as tough as you want it to be, and she occasionally rebels against having to practice something over and over again. I think it's good for her to have the challenge.
