I left in the Spring of 2002, when 9/11 was still very fresh. For whatever reason, i was really numb to the events of 9/11. I just was beyond caring much about anything at the time, i was so burnt out on JWism that I felt dead inside, like a zombie.
I never fear that somehow JWism is what the leadership trumpets it to be - a system of mental constructs which one must hold firmly to -- and continually demonstrate ones holding to in various ways -- in order to not be killed by God when God decides that it's time to start raining fireballs from the sky and opening up giant cracks in the earth to "destroy" all those who don't hold to the same mental constructs.
That said, I do fear the financial/social/governmental collapse of the United States. I've carried that fear since I was a teenager, and JWism was the only thing that ever gave me a measure of relief from it.
