I'm glad I'm not the only one with this. I call it The Mindchatter. Like you cant stop thinking about it, arguing the theology in your head? First thing you think of in the morning?
Mine eased off when I found an outlet to explain the JW world to outsiders. (I chose a Q&A website Quora).
I found laughing at it helped to. Making fun of the GB, making jokes about the pictures in JW literature and basically making whole comedy scripts off the bizzare-ness of the JW world.
Maybe it'll never disappear entirely.
