Hey whathehadhas, I understand your feelings, I've had them too. We missed so much, then you are out in the world and you look the same but inside you feel so different. It hurts me too not just for myself, but the ones I grew up with, not so young now, still in.
Years after I left I was at university and I did some mental health subjects, I learned that a lot of mental health issues surface in early adolescence and some people effectively lose years of their lives, and have to "re enter" the world in their late 20s.
I was fascinated to learn that one of the biggest problems was not the stigma of mental illness, but catching up on the time lost.....social development, the things you were meant to go through & didn't. For example a guy might be in his late 20s and his social development might be that of a 13 year old. He then struggles to reconnect with his peers, he's left behind......didnt go to college/date/travel........sound familiar??
I remember sitting in those tutorials and having one of those lightbulb aha moments....that's what lots of us xJWs are like!!!!!
You havent had the "normal" type of upbringing, but its up to you to raise yourself from now on.
Do not ever blame yourself for time lost - its not your fault!!!
It sounds like you have some good plans for the future, good luck to you!!
