Your upbringing does stay with you especially when discussing it with others. Its all we ever knew and lived our lives along with it. I was not a little "robot" like other children my sister and I misbehaved at meetings as we were so bored and I could not connect with a God I could not see and who I felt had not cared for me and protected me as a child.
I felt it was the right decision to leave it and my conscience was not affected when I looked into other religions and researched the "life after death" philosophy.
I did not raise my children in any religion, I suggested they keep an open mind and make their own minds up as to what they wanted to believe. Its a little like forcing your children to eat vegetables, it could put them off for life!
It was not until lately when I have read about the effects of being raised in a cult, just how much it has unconsciously had influence on my thought patterns and views of people and relationships. I am shocked as I had spent most of my life thinking that I was free of it when in fact I am not.
Of course being shunned by your JW family does have an effect, as seeing other close families is a constant reminder of the life you could have had and all that was taken from you. Very sad.
