Dear Sue, welcolme to the forum, first and foremost you do not have to make any hasty decisions, now is the time to take a deep breath and a bit of a stock take of your position in life.
There is a lot of good advice to be had in this thread and forum in general, I recommend that you dig deep.
All of us here bare similar emotional scare tissue and many have been through similar issues, there is plenty of first hand experience here.
I would strongly recommend that you have a good look at the JWfacts web site before you invest heavily in getting back into a high control group where you will likely be seen as "damaged goods" by many.
Being a convert (like me) you have a huge advantage over many in that it will be relatively easy for you to make new friends with normal people, Think of this event as a new opportunity in life.
All the best.
