Bonafide,
I feel for you.
You have done well it telling that sister what you really believe. Just stick around it sounds as though you are coming to terms with what the organisation has done to you. It's hard and it's a long journey.
But for me, after learning and scrutinising everything i have held dear i cannot go back to what is essentially a fake way of living.
In answer to your question though, was my entire life a fake?
I would say that i am now a product of my past (psychobabel i know). But living that way of life has made me the person i am today, so i have no regrets about that life. Essentially the whole of life for me is a learning experience. It will take time to come to terms with the JW life but stick around, we've all been there.
Paul
