macys, I don't see anything wrong with going back to get your family back and then trying to fade. I do think it will be hard to get reinstated since you'll be frustrated knowing TTATT.
And Cappytan's question is right - will your family shun you if you fade? Some do and some don't.
I wish you all the best. It's totally unfair and disgusting that this religion splits up families. That shouldn't even be allowed.
