Have a support systemin place BEFORE you walk away. Make some "worldly" friends at work or somewhere;, find a therapist if you can; get close to non-JW family...people that you may have looked down on before...people you can talk with....you will need all of them and more to get you through the mental anguish that follows you...especially if you were raised as a JW. It's harder to do after you leave. If you don't you end up being in a "no man's land" for a time. The more time you have invested as a JW, the harder it may be.
People who were as involved as I was in the Watchtower Organization do not just get to "walk away" from the Organization.
Snakes, you are ABSOLUTELY and unquestionably correct. I know because I was able to do the above and my transition has been nearly perfect. Further as an elder it was not possible to just walk away. Both in my own mind (as I felt the need to warn my friends, some of whom left) and because uber elders saw me as an "apostate" and felt they needed to protect the congregation. But even if one can walk away, the transition socially is very important to make before one leaves. Let both lives overlap. It is the shrewd and practical thing to do. If you are in a judicial situation, don't let them disfellowship you. Repent, even if you have to fake it. Then fade in such a way that you preserve your emotional health. If you don't believe it anymore, again fake it while planning your exit. It will be well worth the effort later.
