Hi KingdomEvader - Welcome, welcome, welcome!
I feel for you mate. I was in your exact shoes a few months ago. It's a tuff slog being awake and being an elder. I could only do it for a little while before stopping completely, once I knew it wasn't the truth my conscience wouldn't allow me to keep peddling that crap.
It takes a lot of guts to make a first post here so I can see you have it in you to get through this... it will be rough going for a while though unfortunately. We're all here to help you through it though. The people on this board are amazing and full of compassion and empathy as they have all been where you are. They have helped me and Mrs Stumpy immensely as we have made our way out.
How do you spend your time in field service? I've just been walking up to peoples doors, PRETEND TO RING THE DOOR BELL, (never knock) and then leave. I have avoided talking to so many people that way!
That's what I did too. When my wife woke, we would do it together we would make up the number of mags we "placed" and have fun telling the crazy zealous ones how awesome a morning we had. One morning one of them got so upset that she hadn't talked to anyone yet she asked if she could take what was supposed to be my next house... we swapped places and she found no-one and I lied that the house she was supposed to do turned into a potential bible study! She was so upset and jealous Man did we laugh about that. That's the only way I found to cope, make a game out of it and have some fun... otherwise you will go crazy.
We haven't been in field service for over 2 months now, believe me you're going to love getting your Saturday mornings back mate!
Shepherding calls are a nightmare... the ones I go on, I'll just talk about love and how to not be a terrible person. I hate going with elders that just want to drive in the "go to meetings, go in field service, do more" mantra.
The last few I did I told the elder I was with we are just going to ask them how they got the truth and then just listen, nothing more. Both parties loved it and I got out of the pressure of having to say something I didn't believe in anymore.
What about service meeting parts and public talks? How do you do those things with out raising suspicion or losing your sanity? If I were to listen to one of your public talks... would I know you were an apostate? Do you "lie" and say "support the GB" to avoid suspicion? Or do you make the talk as general and mainstream as possible and eliminate most of the cult speak?
Like mentioned before, just get rid of the ones your conscience won't let you do and stick to the generic ones. I actually had a lot of fun with my last public talk. I made it very practical and only used scriptures that contained good principles to live life by, whether you believe in a god or not. It went over really well. My last assembly part I had to give was more difficult as the outline had full on cult indoctrinating GB lingo in it. I just watered it down and eliminated the cult stuff like you mentioned and no one was the wiser. As someone mentioned above, the watchtower study is the hardest. If you are doing that I suggest getting out of that assignment asap... it will be torture otherwise.
Keep reading and posting mate.
