I am getting perilously close to the point of resigning as an elder as it is all getting a bit too much.
I can certainly feel for you in this situation.
I also, some time ago, was an Elder and had got caught up in the "company man" spirit.
Fortunately, I came across this forum and was brought to my senses. I stepped down as an Elder
giving reasons such as pressure, to spend more time with the family etc which was in itself not false
but not really the main reason. I had began to hate myself for the way I was feeling " superior" as an Elder and that
I had pushed aside the " humaness" that should have been in my life. Replaced with putting emphasis
on hours in the field service,meeting attendance, completing assignments,encouragement to pioneer, etc etc.
But when I was not an elder I realised that credibilty as a witness also suffers.
How some ( not all) reacted as if I had rejected a privilege from Jehovah and that I should have stayed on
as an Elder. My goal was to try to reach others to help them understand TTATT but I had no credibilty.
So I put some effort into trying to show I was a "spiritual" man and finally I was appointed as a MS.
From that point things were much better. I had the credibilty that comes with the appointment and I am able to
speak to others about some of the shaky teachings ( ex: overlapping generations) and some actually listen, as well
as the fact I didn't have to attend all the "brainwashing" Elders schools and Elders meetings.
So I would consider carefully whether you should step down. I know how you feel ( as much as anyone can do that)
and I know that it is really difficult to carry out assignments when we know what we know. ( I conducted the WT too)
But I wanted to reach out to others and help them to realise that there are other ways to please Jehovah and serve him without
having to follow the GB's rules and regulation to the "T".
As a MS I can do that. ( Of course this has to be done carefully) but I now feel that I can be of help in the congrgation and
especially when others express doubts or complain I am ready to show that I understand how they feel rather than jumping
on them with WT quotes as I used to.
Just some thoughts that might help
BTW this site helped me a lot too
