I really believed "the Truth", even though I rationalized things in the beginning with the 'the organization is made-up of imperfect people' mantra. But I remember reading and reading, and then I left the JWFacts article on the WT being a cult for last, especially because I wanted to read it very carefully.
I still the remember the mixed emotions of relief, anger, frustration, etc. But, it took me a while too. Nevertheless, I remember it very clearly, when I got to the end of that article the evidence was overwhelming--I could not deny the truth anymore.
I've never looked back ever since.
