Seeing you had your daughter tested, I would talk to the teachers in your daughters school and see what you all can do to help her. Who did the testing if you don't mind my asking?
Have you talked to your daughters doctor to see if there is anything he/or she could recommend?
One thing I would not do, is let her quit anything she does not get right from the start. I would make sure she keeps on trying. Encourage and praise her often, even for the little things she does accomplish.
