miseryloveselders post well illustrates a point in the departure process. He feels utterly trapped because he thinks he still has to provide reasons to the other elders for his decisions. Until someone has moved on from mentally acknowledging the authority you give them, resigning, skipping meetings stonewalling shepherding is too much of a challenge. Once you've stopped feeling you have to explain your actions it's a lot easier as vivalavida shows.
Not explaining to spouse/family is more of a challenge...
