You are not a fraud, you were eceived and lated like we all were. I glad you are feeling better. Stay in touch with your children, perhaps you will all grow closer as time goes on, they too are healing from being involved in a cult. Send letters and emails, even if they do not respond. I am not as close to my children as I would like, but they are adults with busy lives, and that is the reality of relationships, they will love their children more than you, just as you probably loved your children more than your mother. I have apologized to them for ever being in this religion, and I have tried to make it up to them as best I can, and that is all you can reasonably do.
Take care, and I hope you find some peace about the situation.
