Stuck, I know how you feel, we all struggle with this. The way I cope is I think there are so many ways to screw up your life or have it screwed up for you by circumstances, not just being in a cult.
Being born to rubbish parents, being born in a war zone, being born into poverty in a developing country, being depressed because of circumstances in our life and trying drugs and becoming an addict or catching AIDS. What has happened to us is recoverable from. Given time and work. Or should I say we can survive it and live a happy life.
People are born into circumstance beyond their control, thinking globally and studying history has taught me this. Not everyone has a mind open enough to cope with this idea but from reading and liking many of your posts I think you do.
We could stay angry and bitter for the rest of our lives but if we do that they win. I refuse to let this cult win.
Take care of yourself xx
