Hi Hasti,
I am not in the same boat as you, but do know someone who is, and who has gone through what you are going through with your daughter. He is a very close friend, so perhaps I can have him come on and post to this board, and see if he can give you some support.
Good luck, and most of all DO NOT GIVE UP. She needs you now, and I can see you are all there for her. Muscular dystrophy is not the end of the world, I hope that if it has to be one or the other of the two, that it would be muscular dystrophy. (only because I know more about it versus CP)
Again, I will try to find out if he can post here and at least give you some moral support.
Take care, and God bless you all.
