Unfortunately my story is not as noble as most. I was disfellowshipped when I was 24 for having a one night relationship with a worldly woman. I was an MS. My mother was anointed. And, at the time I was close to becoming an elder.
It wasn't TTATT that woke me up. It was the fact that I felt so guilty for having sinned that I felt unworthy of forgiveness. I believed for years after I deserved to die at Armageddon. So I stayed out and did not try to get reinstated. Instead I spent my time working hard and learning. And over the years I came to realize the JWs for what they are - i.e. yet another religion that claims to have truth. A dime a dozen...
But over the years things changed. I learned more. I thought more. Being disfellowshipped was the most painful thing that has ever happened to me. And I lost my family and friends. But, if I hadn't been disfellowshipped perhaps I would still be in or lamenting years of wasted time.
I admire those who walk out on principle. I don't have such honor. I got kicked out and never looked back.
