Nosferatu, your story is really sad. Where did you live? What was your environment like? The only thing to regret about that is that you were associated with the Witnesses at all. If you hadn't, you might have "broken out" and become what you needed to be a lot sooner in order to stop the abuse and to not put up with all that crap.
I was lucky. I was relatively popular and went to a lot of parties (we called them get-togethers) with the Witnesses. The problem was that I wouldn't have gotten laid if an orgasm ran me over. I was horny enough but I was too repressed by my parents (it had to do with my native culture) and would imagine that the world would come to an end if I embarrassed them. Looking back, I wish I had put my foot (or any other part of my body) in it and suffer the consequences. I could have saved myself years of a really f'd up time being a Witness.
My dad was not a Witness but he was supportive. He didn't push, though. Even so, he was very strict in my younger years. I wish he'd care enough, instead of just sitting on the fence, and pushed me to go to college instead of pioneering after graduating from High School.
It does sound to me like your dad was trying to be saved vicariously. He seems to be one of those do-as-I-say-not-as-I-do kinda guys. You should have called him on it. But, I realize that that might have gotten you another beating. I would have taken it. Anyway, it's all water under the bridge. Revel in your good memories and screw the bad ones. Think about the person you are now and what worth you have that is laudable. Hang tough.
Etude.
