Maybe you should look for another therapist who deals with and understands Cults and how to help those leaving them..
It shouldn`t be up to you to educate your therapist that JW`s are a Cult and then for her to help you ?
Dump her and look for one who knows where you are coming from .
Welcome to the board Straw man ,but you are behind the 8 ball if you have to educate your therapist that JW`s are a cult religion , you need to see someone more mature and more experienced for you to get the help you are looking for.
Take care my friend and best of luck.
