A very big welcome YinzerDad!
Your story mirrors mine and many, many members here.
We cannot get back our childhood. Even in JW promised Paradise, we cannot revert back to childhood and experience those little things and like you point out, the ability to become passionate about something that leads us to something bigger and better in life.
I look back at my childhood and Mom was the classic uneducated, struggling, and miserable person which is exactly what the JW's look for. The vulnerable! And therefore, I join you in regretting the fact that I was never afforded a truly free and normal childhood. Those that are on the outside looking in cannot possibly understand but you sum it up nicely when you write:
"What I can't get back is my childlike ability to imagine what I want to be when I grow up. Because that's what kids do. And it is a fundamental point in childhood development because that's when you develop a passion for something. It could be a passion for leadership, for sports... something. I was never afforded the opportunity to do that. Because the end was nigh."
I feel your pain Yinzer, I and many of us here. And I, like you also attended college. Hang in there. And live life. Live everyday like it's your last day. Live it for yourself. And live it for those that never got the opportunity to do so.
