First of all congratulations that you managed your exit of this cult.
You are free now, free to embrace life and live a life with all its joys, pleasures, problems, doubts according to your conscience and without a set of manmade religious rules.
Now concerning spirituality or belief in god:
You don't need to jump to quick answers or solutions. And if you don't know something (if god exists or not) you might leave it open for the moment. It is also good not to know everything and leave it open and meanwhile use your energy for a good cause.
After leaving the JWs I lost my belief in organised religion, the bible and the god of the bible.
I can understand when someone sees himself as an atheist or agnostic.
However I still believe there is a higher force who is behind the natural laws of this universe (or many more) and I tend to believe this force or god is personal too.
Why do I believe that? My view of the world, life, love and a looking at near death experiences bring me to this conclusion.
I wish you all the best in your life.
