She obviously is very intelligent and strong to keep her wits about her during the accident or she probably would not have survived, as she said something to the effect that she knew she needed to keep away from the motor while trying to get out from under the boat. And didn't her parents say it just grazed her head, so could have been even worse?
Prayers for her healing and success in getting a prosthetic which works well for her mobility. Also for her family dealing with the stress of such a close call on the life of their daughter.
