Welcome Sibboleth. I've also looked back on my life and felt the rage over a wasted youth. It's not easy to think about what you COULD have become had it not been for the Watchtower organization's insane rules.
It's never too late though. Go back to school, get your degree. I'm doing it right now, and so are a lot of others here.
The best way to let go of the past is to take control of your future.
