I have sometimes missed the feeling that comes with believing you have all the answers. When you believe it's the "truth", everything is laid out for you. No guessing or having to look for answers to meaningful or difficult questions. Just go to your WT index...
I sometimes miss the feelings I had after the assemblies and some meetings, especially after giving talks. But again, those were predicated on the notion that the JW's were God's organization. It felt like I was in God's organization, many times.
But I finally did my homework. I honestly, sincerely and thoroughly examined the faith from all sides while remaining objective. I had no bone to pick with the organization or reasons to leave it. I just never knew how dead-wrong they were, and, just how often they were so very dead-wrong. I never realized how conrolling it was either. Afterall, I was used as an elder and a very busy person with many responsibities. That "buzy-ness" keeps you from thinking too much, IMO. My reasons for rejecting specific JW teachings were as sincere as there can be. I could not just go along with them any longer, once I was fully informed.
I do not miss the social aspect very much at all, like some others do. Though there were a few nice relationships I sometimes think about. But today, I can see just how conditional they all were. And THAT is major turn-off to say the least.
Overall, as one that came into the org on my own, you cannot spend over 16 years without missing some aspects of it, in my opinion. But also overall, my quality of life today is better than when a Witness. Freedom is a valuable thing. Taking responsibility for your own beliefs and decisions is another good thing. Cutting the JW leash definitely a good thing.
Though not always the easiest thing.
