Since I picked the screen name lrkr, I guess I'm obligated to respond (will have to change this name one of these days)
In a word, people. The people in the org are good friends of mine, family are all good people (and very JW). The thought of losing these relationships pushes me to put up a fascade. But that gets more and more difficult. Going in service and asking people to study and become a JW was the first difficulty. I just didn't want to subject them to it. That feeling of "I just cant anymore" progressed to parts, commenting, conducting the BS (esp in the Revelation/Imagination book), and finally to just sitting through meetings.
I suppose lurking is the first step in a journey. Growth is good. Lurking is the first step.
