Sail Away.
That is a sad family story. I am sorry you have been treated so poorly.
You are a better person than I would be. After treating my family that way, those ungrateful Grandparents wouldn't NEVER hear or see my family.
It is truly unbelievable that these people can treat their very own family this way. They brag about how LOVING they are (makes me want to scream).
The sad thing about it is if the Grandparents need someone to care for them or to be put in an assisted living facility...the congregation or the Grandparents would then contact you to take care of the details. I have seen this happen alot in our area.
This is a take, not a give, organization.
You are in my thoughts. Hang in there.
