Been reading this forum for some time, but having read this thread caused me to finally register (BTW, as a small introductory: I'm from the Netherlands, in my thirties, wife, kids, born-in, not doing field service for about 5 years, fading).
In contrast to what some people said about expressing their doubts before the age of 10, if've never really recognised my doubts at that age as being doubts. I just really wanted to believe; if everybody else believes (mom, dad, older brother, older sister, nice people from the congregation), then it's probably just me. 'Maybe I should try a little harder'.
First real doubts appeared in the form of anger when I learned that an elder criticised my father (who was also an elder) for not kicking me out of the house because I got a JW girlfriend while not being babtised (BTW, the JW girlfriend is now my wife and eventually I did get babtised, though I did not know about this elder's ideas at that time). That was the time I started doing some research on the internet and needless to say, I had even more doubts.
