When we left the organisation we lost many people who we had viewed as friends and had to start again. We were in the organisation for 40 years so they had pretty much controlled our youth and held us back. However I have put a lot of effort into rebuilding my life and finding new friends who will not drop me the minute I disagree with them.
I try not to look back as there is little of value behind me and so much to discover ahead of me. Personally I could not go back, I found the basis of my faith was built on a lie, that the people responsible for my spiritual well being didn't really care about their followers and that my children were unimportant to them.
I can honestly say that by embracing opportunities it helps recovery. You have time to explore spirituality and look for answers without returning to the organisation. Fear of other religions has been programmed into us and whilst it is good to be skeptical you can try talking to people with other faith perspectives and those who have none to see if this helps you gain an insight.
Depending on where you live there may be a thriving community of exJWs happy to hear your story and talk about where they are in their lives and how they have recovered. You have made a start reaching out you can build from this point.
