I am very sorry to hear that your friend has been df. If i were you, I would tell her to start examining the teaching of this group(JW). Check out a book Jehovah's Witnesses Answered: Verse by Verse by David A. Reed. It showed me a lot of how the group was not following Christ's examples. It even touches on the df stuff and how it is destroying the church not showing the restoration power of Jehovah.
With her time apart from the fellowship, she can examine all she has been taught.
