Hi and Welcome tiredroadie,
Your friend is being love bombed at the moment and being shown a lot of attetion. It's commendable that you care about her so much. JWs are in a cult. It's a high control religion and you can read more about the history of the religion and the doctrines on jwfacts.com
Does she have parents close by? If you know them well try and explain their daughter needs their attention.
I was brought up Jewish and converted around 20yrs old when I was at uni, about 20yrs later I left. My full story is on youtube, if you want to listen to it (it's 35 mins) let me know and I will stick a link up.
