It took a lot of digging and reading for me to little by little get rid of the mental residue left over from being a life long witness. It is quite an accomplishment to rid oneself of that " But what if they really are right ?" feeling. The best thing for me was seeing the misinformation in the old literature such as that old 1984 Watchtower with all the (long dead) elderly Bethelites looking heavenward, enntitled, 1914...The Generation That Will Not Pass Away. Their own publications containing misinformation, coupled with a death of a my Dad over the blood issue as well as the injustice treatment of a family member by the Elders gave me the courage to act on what I had realized decades ago. If someone is carrying around Watchtower learned guilt, I think it's best for them to rid themselves of it by looking at all the mistakes, lies and wrong infromation in the publications from the past in which they learned "the truth" in the first place.
Too bad there isn't one book or collection of information where it's all contained in one place.
