There are plenty of good things in most experiences of leaving Watchtower behind.
I went through a rough period when I left. I was told by JW's when I was recruited that I had been seeking deeper truths about life, the universe, and everything. And of course, they had all the answers about an issue of universal sovereignty and why bad things happen to people due to Satan and the demons and YADDA YADDA YADDA. But as it turned out, I was asking a simple question, which was "Who am I?" That's what people really want to know.
Once I realized that, I was able to proceed with my recovery from Watchtower quite well and to pursue happiness.
