Sasha I enjoyed your story! I remember searching on the Internet years ago too for 'how to leave jw's'...at the time this fading approach was new. It took me a long time to find that suggestion from someone. But whoever it was, described it so well, I was like 'yeah! That's what i'll do.' And it suggested a move to aid the situation. It wasn't on a forum, I think it might have been on ask.com. Whoever it was, if you are here, thank you!!
Sasha, welcome. It sounds like your parents have sort of accepted that you are mentally out.
