WTL, you'll find that when people leave the JWs there is not a single destination that they all go to. Some become Christian (of a variety of denominations) some become atheist, agnostic or deist. Some explore eastern religions or pagan religions. The idea that there is one organization that's supposed to lead you to God is not Biblical. Keep doing research and you'll see why I say that.
What you choose to believe is up to you. Use both your brain (what makes sense) and your intuition (what feels right). I'll give you an example of what makes sense: You love your kids. You want them to succeed. Would you, then, make it difficult, close to impossible even, for them to please you? Why would God feel any different about his children? If a particular teaching violates either of these senses, don't ignore it. You should be really satisfied about any teaching you're expected to put into practice in your life.
Take some time to explore different religious concepts. What are the odds that anyone has been born into the correct religion? There's no harm in learning what other religions teach to determine whether you believe them or not.
If you want to know how God got here, I don't know if there's anybody who even claims to have an answer to that. That sort of question has led to some believing that God does not exist. If that's the route you go, that's fine, too. I think that God-focused relgions do require a suspension of disbelief, otherwise referred to as faith, on issues like that.
Personally, I have come to the conclusion that the Bible is a human book rather than a divine one. But I really enjoy discussing it and hearing interpretations of scriptures that differ from what I was taught as a JW.
Go ahead and enjoy this period of spiritual exploration without feeling that you must immediately conform to whichever teaching is The Truth. With so many different teachings on the earth, how would God expect you to know what's true without first examining them?
