Start studying the bible from a purely academic stance from scholars like Daniel B Wallace and Michael S Heiser. Something you would actually found taught in a school of Christian theology in a secular university. Try and understand the new testament though first century Jewish eyes. I think you would be surprised how interesting it all is and also how incredibly stupid WTS theology is.
Also don't confuse ex-witness as ex Christians either. They were trying to disprove the bible as JWs and really aren't that far removed as ex Jws, complete with the hated filled arrogance they had as JWs.
