To address the question the OP posted (and not to be sidetracked by Reniaa's myopic bletherings), my son was deeply affected when we left the Witnesses. We had to speak to his teacher and the head teacher at his school to explain his sudden change in behaviour. He'd suffer panic attacks if he heard things like heavy machinery in the distance as he'd think it was Armageddon starting.
I should point I, we never, ever stressed Armageddon to him when we were Witnesses. I refused to study the WTS approved publications and would always speak about Jesus in our family study, or focus on something fun like nature and the planet.
So, where did he pick up the Armageddon anxiety?
