This is very difficult to answer because none of us can anser authoritively from both sides.
But I was bought up as a JW from a very young age,neverknew anything else. My brother always thought that he missed out on birthdays etc, I never did. I tried to be a good JW but when I left it took me along time to come to terms with much of it. I believe that mentally and emotionally we have missed out on so much that we are affected for life.
Why do we all post on this site? Is it not therapy? Are we not all affected and seeking comfort from others who have suffered in the same way, whether we were born into it or came in as adults.
