Good post.
We, as ex-Witnesses, lament our missed opportunities and blame the society for many things.
But, this idea can apply to anyone. There isn't a person anywhere in the world who hasn't experienced some problem - many of which were far greater than we have faced.
As you mentioned, we are the sum total of our life experiences. Part of who we are today was molded by the organization. If we like ourselves, then part of what we like came from them. If we don't like ourselves, well, like they say, today is the first day of the rest of your life. Fix it.
