Anything you say will be forgotten in 5 minutes & all they will recall is that you are an apostate or mentally ill.
You have to remember that you are not dealing with sane people. It doesn’t matter what is real or what makes sense. They will never play by the rules that a reasonable person would follow.
Basically, decide what you want and only work towards that goal. If you want personal attention, go for it & play the game. If you want them to understand anything real, you are wasting your time. If you just want out of the org, just leave without doing anything that will cause you needless stress. If you want to keep peace in your family, continue the quiet fade.
Dont harm yourself by giving them ANY perceived power over you.
