(((caligirl)))!
I've had several confrontations like that with my mom. Luckily, I've never been a JW, so she isn't ordered to shun me. I think I actually had her thinking at one point, and then when she went to ask her elder some questions, he told her to stop talking about it with me! Total brain control. All you can do is give her the unconditional love that she will NEVER find in the Watchtower. I will say a prayer for you.
