I could go on to tell you to start with assuming nothing, questioning everything, doubting most everything.
But instead, I will appeal to common sense. If God saw your struggle with JW's and discovering that "the truth" was a lie, and if He knows how faithful you wish to be in finding the way, He won't be angry if you take your time.
Relax a bit, search. Start a journey of discovery. Include skepticism of the Bible and include science. Include philosophy and alternatives to Christianity. Do some heavy research on cognitive dissonance and cults. Enjoy finding out what the real truth is. If God is worthy of your worship, He won't smite you for wanting to find the real truth.
