In my conversations with individuals in their 50's and 60's who were raised as JWs and left (w/o being baptised), they seem to have been adversely affected by the "fact" that the huge buildings they could see in the distance were going to be destroyed and all the non-jws were going to die. I have limited contact with JWs but the striking similarities of childhoods being affected by the fear of death that was going to befall non-JWs seems to be a common theme.
I'm sure that my imagination of this type of childhood couldn't possibly create the physiological effects from which you suffer.
I hate that you still suffer.
