Hi Molly - It's an understandable reaction to throw throw baby out with the bath water. I would be interested in hearing why you became an atheist after leaving Jehovah's witnesses.
When I left the Watchower I was not bitter towards them or religion. I visited many Christian churches and restudied the Bible. I then embarked on a 10 year study of world religions including eastern, Zen Buddhism and Tao. Most faiths present a philosophy for living in harmony with ourselves and other people. I am no longer attached to any religious movement and no longer pray to a personal God.
Even so, I find that understanding can be enhanced by being humble and open to possibilities. Having lost your faith, you now have to find balance in your life. Gentleness, love and kindness are qualities that are a part of most believers lives. What they share can be beneficial to you, and help you to maintain your awe of being a part of something wonderful.
Please take your time and don't rush to find a new lable for yourself.
