JWs know nothing about respecting personal boundaries because their religion teaches them they don't have any. They can be told how to live every personal aspect of their lives by an organization and their conduct is policed by elders.
You need to introduce your mother to the concept of personal boundaries now! If she forcibly moved into your house then she has no respect for you whatsoever, you need to teach her to respect you. It's not going to be easy but the sooner you start the better.
