Sound, Stage, and Mics were dumped on me the first week, then a month later I was assigned as a Watchtower and CBS reader, and I was put on the schedule to pray at the meetings. (Which I felt really bad about because there were brothers who had been in that congregation their whole lives and hadn't got to do any of that stuff!)
REALLY? Everywhere I went, they couldn't hand those assignments out fast enough to any baptized males, young or old. They might have taken away reading the Watchtower if the "brother" wasn't tolerable, but the rest of that is ordinary privileges. Why do you suppose your congregation is so different on that?
Anyway, I think I get what you are saying. While I don't say anything like "coping with atheism," you concerns are similar to what I went through. Jehovah supposedly saved my life (long story) and gave me a purpose. But to come to the realization that He wasn't even there threw me back into a depression over issues I avoided from before I was a JW. It took me time and serious soul-searching. I went to counseling, but it wasn't over the atheism, rather it was over those issues.
For atheism, I read many books and watched many videos. Everyone has to find their own path, so enjoy it rather than "cope" with it. My wife is not "hardcore" in many ways, but she does seem to be in the JW's for the longhaul, so I have to cope with that also. I slowly shifted to more freedom to be myself and ran into some snags with my wife. I honestly think I would have divorced her and had nothing else to do with JW's were it not for the need to try to keep contact with my JW mother, so I faded out from the congregation. Don't get me wrong- I love my wife. It's just that I might have thought both of us would be happier if we went through all the pain of divergent paths all at once. Since that did not happen, we have learned to be happy and not discuss religion and beliefs. I don't really say anything to her about being atheist, but I am sure she knows.
