Welcome breakfree,
My daughter had to sit through a jc even though she was not baptized, she felt soiled afterwards. I woke up three years ago and went to see the danish movie Worlds Apart about a jw girl and her family, I was with my daughter and we were both crying when they showed a jc scene. I did not know how bad it had been for my daughter and she was 18, I cannot imagine how horrific it must have been for you at 13.
Hope you continue to heal and move on, it took me two years to get it out of my system to the extent that I now have peace. We have a great family life now and I shudder to think of how it used to be.
Hugs
Chicken little
