Darkknight,
I'm sorry for your losses, and can empathize with you and your wife. There is a large army of sisters and brothers that have lived with the loss of child through miscarriage. Its one of those terrible things that for some reason the expectation is for you and your wife to suffer in silence. When my sister lost her second, I berated the elder body for being so clueless and uncaring especially when her hours slipped. It was one of many things that woke me up.
As you are the watchtower conductor it will likely be very difficult for you to step down as they view you as the best teacher, per the instructions in ks10 and the last CO visits. But you can do it. I was only the TMS conductor so it was a little easier this year to step down from it. I just told them it was too stressful and I needed some time away from the position. They won't complain too much if you say its just too much for a bit. Just remember its a private family matter that my wife and I need to work on.
I too had a bit of a crisis of conscience, when the WT asked me to bend the rules I could feel my grandfather roll over in his grave and I knew I had to get out. It took two years to slowly wake up my wife's mind to critical thinking, and its a step many profess that works. I did not want to loose those 20 years together (we must have gotten married the same year). Once her mind was awake to thinking for itself at all worked out.
For your sake, do the research you need to do at this stage. I'm not sure your ready yourself to take that next step of spirituality that many are not willing to take. jwfacts.com helped me reason with myself and understand the true history of watchtower. For me that was a first step. But take some advice from others as well about getting away and chilling. Good luck.
