I, too, found that I was unhappy, but my belief was that I had to stay in the organization, since it was the true religion, whether I was happy or not. The alternative was a fate worse than death. A time came when I finally decided to question my assumption that it was the true religion. Facts had to be the deciding factor, not merely my displeasure with the way things were said or done in my personal experience.
It stuck in my head that the Society was repeatedly warning people not to talk to apostates, so I figured there had to be some reason they were so afraid of us doing that. So I started with the deadliest of apostates, Google. By the time I was done researching on my own, I was pretty convinced something was wrong. Learning about how cults work (via Steve Hassan's excellent book 'Combatting Cult Mind Control') and reading the brilliant books of the late Raymond Franz ('Crisis of Conscience' and 'In Search of Christian Freedom') pretty much convinced me it was time to get out.
Unhappiness is a starting point for leaving, at least for some. I needed facts to be sure about what my decision should be. If I hadn't found anything solid, I would still be a JW right now. Unhappiness may actually be enough for you, though, as it is for many people. Whatever the case, I'd still recommend at least reading Steve Hassan's books, just for reference purposes.
Glad you're out. Thanks for sharing. And enjoy the excesses in booze and women, at least until you become a pig farmer....[rimshot]
