My advice would be to focus on peeling back the layers of indoctrination for a while before you start looking to join another group/religion/belief-system. There's no rush - take your time. The JW indoctrination that time is short can linger even after you lose your fear that armageddon is imminent. Spend some time on introspection, and examine your beliefs and why you believe them. Follow each one to its ultimate source and if the foundation of some belief turns out to be that the cult is true or based on something the cult told you, set that belief aside for reevaluation later. Get to what you know is true and then start building your way back up from there.
While you're doing this, try things that you couldn't as a JW. Maybe instead of prayer, try meditation. Have a birthday party. Develop friendships with normal people. Watch bad movies and sleep in on saturday morning. Try things you've always wanted to, and things that make you uncomfortable at first.
Between introspection and experimentation you'll start to find things that give you meaning and what (if anything) you want to believe going forward.
