First of all, welcome! And it's great that you've found a good decent man for you and your boys.
I developed a severe anxiety disorder. It wasn’t just being anxious all the time. It was severe panic attacks combined with Emetophobia (fear of vomiting or seeing vomit). Looking back now, it all made sense as Emetophobia is about fear of losing control. I was quite ill with this disease as it lead to anorexia. I was afraid to eat too much because I felt a full stomach could cause me to vomit.
THIS! /\ - I had exactly the same thing! I never realized until you said it was probably fear of losing control. The emetophobia vanished when I left the JWs.
You're the second person I've read about this week who's left. This is good news indeed.
