They key to free yourself from the organization is having mental clarity of what is happening in relation to the Watchtower, inside and out. Their basic concept is that they are God's sole organization on earth. There really is no basis for anyone to make that statement. All religions say this in different ways and forms and the ones that believe it, fall victims to any organization that proclaims authority from God.
Once you understand that Jehovah's Witnesses have no authority over one’s self, that’s when the process of liberation starts regardless of all doctrinal errors they may have.
It is not a matter of doctrine, it is about understanding that they are just one more organization in this conglomerate of religions, and highly detrimental to its members.
Forgot to mention that learnig TTATT or the Truth About The Truth, is not for the lazy people that are not willing to do some deep and thorough research.
