The majority of those leaving, from what I read here and on other boards suffer two losses when they separate from the WTS. One, the loss of friends and family members who remain Witnesses and two a belief system that has no easy replacement. For me, just drifting away over time worked well. Because I had no congregation affiliation, after awhile, and after reading Crisis of Conscience, I felt absolutely no need to formally disassociate myself because that would have made it hard on my family. I don't believe I owe the WT goons another ounce of pain, discomfort or anguish. After many years of examining other belief systems I have reached a comfortable state where I am. If somehow elders wanted to visit with me, I'd refuse to talk to them. If they came to my door I'd order them off of my property. If they in any way bothered me or my family after my previous refusals, I'd plan an appropriate punishment for them. It might involve a family pet, a nasty rumor to their neighbors, who knows? They would pay a price too great. I view them as the enemy.
Leaving for me has been NO problem at all.
