Completely understand where you are coming from. I was never directly affected by the backlash of leaving the religion, but I did see many family members get shunned, and this hurt me. The trick is (like others have said before) to channel your mistrust, hate, hurt, whatever it is to something positive. Although I would like to warn the world about Jehovah's Witnesses; if I did I wouldn't be any different from when I was a witness, warning the world about the end of days. Just be true to your self (don?t feel that you have to please others to be happy) and don't stoop down to their level of thinking.
