Joliette,
Don't worry about replacing your membership as a JW with another church connection.
When you make the move, just go. Take time to do plenty of research. If you absolutely must go to a church, try the Unitarians - they don't force you to believe anything specific - you could even be an atheist - but you'd have the community support and fellowship you might need. Then take your time figuring out what church, or none, you might want to check out further.
Above all, don't try to replace one group of false doctrines with another set of false doctrines. Take your time - and take as much time as you need.
