Best wishes to you and to Ali.
Modern medicine is capable of doing some pretty impressive things, if it is allowed to.
Good luck in keeping her Dad away from her. I think she can request to have the JW HLC boys banned from her room.
Don't forget that she is YOUR child, she does not belong to the HLC, and the doctor's duty is to "first, do no harm" which means the doctor will be biased in favor of effective treatments, not fanactical religious dogma.
Again, best wishes.
