Cordelia,
I want you to practice saying the following, over and over until it becomes etched in your soul. Say it whenever one of your JW relatives tries to tell you how to live your life.
"Last time I checked, I am ___ years old, and as an adult, with a job and a home of my own, and being the mother of my child, I don't need your permission to _______________."
and
"Didn't your mother ever teach you that if you can't say something nice, don't say anything?"
