It's wonderful that you talked to the assistant coach. Communication can be so important. Kids this age, however smart they are, are still kids, and they often can't accurately perceive and describe their feelings. Your daughter is such an achiever. My DS9 is the same. Even though other people look at him and marvel how much this little kid can do, he chooses to focus on what he is not so good at and feels frustrated. My friends have been telling me that it's really important that I help him relax and put things in perspective. We are working on it.
