you should help her by remember her with her god, and try to make her satisfied and that all people have their own problems, and they are like tests to us in this life, and always when we satisfy and know the wisdom, like what is behind that and what is the message from god to me in that, when we do that our will become strong and when we say thanks god, god helps us and make us strong, and the problems disappear with their selves :) tell her also, just be patient and feel with the god and every thing will be OK, a lot of people who do that overcome their problem easy, and many people who had that disease had recovered from it, so it is just days hard and it will pass and every thing will be Ok inshaa Allah, she isn't the only one and she is better than a lot of people ^_^ also advice her to take honey everyday, as it contains a natural medicine believe me ^_^ God help her and help you in that, wish to her speedy recovery :)

Everyone has her advantage, try to find it. Everything will be better
