Welcome, I read your whole story. You did very well with what was handed to you as a child. I just saw the video for the song "because of you" by Kelly Clarkson. It made me cry because it was about a young girl and how she was neglected by her father and had a lot of chaos because of her parent's bad marriage and how that affected her as an adult, that she was afraid to make choices and decisions in her life.I could relate because of the chaos of my childhood.
You are smart to stay away from the JWs, it's a crazy little cult that has nothing to offer but guilt and a life of being enslaved to an organization. Don't ever be tempted to go back, there are plenty of better churches out there if you feel the need.
You are young and have a whole great life ahead of you.
