One day in 2003 I just started thinking about the existence of god, and all the discrepancies in the bible. Within a month I was on autopliot, my mind was detatched, and a little voice had appeared in my head which just kept nagging at me during the meetings. Everything everybody said at the meetings sounded like a crock. I began to see people for what they really were, and asked myself that had I met them in my normal daily life, would I have chosen them as friends. I decided that possibly 10% of the witnesses at my KH were maybe okay, the rest were just arseholes. Then one day I just drove away from the meeting after not stopping to 'associate', and realised that that would be my last ever meeting. I reasoned that what would be the point of continuing the charade further. The anger and revulsion inside of me stopped me from wanting to go to please anybody. I knew that if I went to one more meeting, then somebody was liable to get punched.
I have since done the play-acting that I feel depressed, disillusioned with the 'Truth', etc. This is just to placate my family. I still get the visits after all these years, but choose to play cat and mouse with them. If they're occupied with me, it wastes thier time, and saves somebody else an unwanted visit.
I don't think I could do the gradual fade thing. It's like trying to wean yourself off poison. If it's bad for you, stop doing it.
