Great thread. Thanks for starting it.
I agree that the culture and teachings of the society do contribute to a heightened state of stress and anxiety.
The very idea that "we alone know the future" and how "all will be destroyed except faithful witnesses" must play havoc with a normal mind. The FEAR, OBLIGATION and GUILT is abundant. (we don't see that until we exit the culture)
It is like cornering a puppy and raising a large iron bar above its head and holding it there threatening to strike it! It cowers in fear and anticipation of what seems to be about to happen!
That is how every witness is raised to feel......
