Nope, never been happier in my life. In fact, I was depressed and in a very, very, very dark place with no love for myself being a JW. Leaving literally saved my life. Can't even really express how meaningful that was for me.
Most JW's don't have a carefree life. There are too many rules and regulations. It's being in an abusive relationship.
I envy no one. If there's something I want or improvements I can make to better myself and my situation, I take responsibility and make it happen. I can do that now that I'm flying free.
