When I was in, there were happy times and difficult times, just like life.. I can say that life is happier now than it was in the last few years before I quit. When I was young and stupid, I had no sex, no mad parties, not many friends, no Christmases but I felt happy in the knowledge that I was special, that God had allowed me to be his Organization and, hey, I was going to live forever in peace and security !!
This is the best answer I've read yet. I think the ones who still believe it's the truth are basically, happy. Whatever moments of unhappiness they experience have more to do with life in general, not simply tied to being a JW. When I still believed it was the truth I was happy, for the most part. It was only after I started doubting, and learned the truth, that I became miserable, to the point where I had to leave for the sake of my mental health.
I think the unhappy ones are the ones who feel trapped. They no longer believe it's the truth, or that armageddon's coming, but for any number of reasons, can't bring themselves to leave.
