Hello CC,
I don't know if there was much I can add. I was not an elder, but lets just say i was a high profile MS, with more responsability than usual, and essentially served as an elder and then some in a foreign assignment.
The idea that you are important and useful is an important one. You and many of us tied that in to our serving the congregation, which lets face it, was 90% dummy work on our part. How much REAL sheperding, REAL help was given? Not because it wasn't in our hearts, but because of what we thought it meant.
There is no way to maintain status and step down. people will immediately treat you different. It happens at all levels. So make peace with this and you will be happy. Regardless of wether you want to continue as a JW or not for the sake of what you feel, good or bad, you should know that you are not REQUIRED to do anything. You can simply say you have decided to not serve as an elder currently for personal reasons. You already know they will meet with you, but the nice thing about being the big dog is this......someone will want your spot. :)
