For some reason I thought I'd have a look see at an ex-Mormon site. Very similar experiences, difficulties, pain etc for them , as us.
One girl made a statement that really stood out, she said that for a born-in , especially one whose family had been in for years , it was like " losing citizenship in a country that contained all of your history, all of your culture, and all of your heritage."
I think that is so true, we leave and are immigrants in a strange land and culture that we know nothing about, no wonder it takes us a while to adjust.
