Sarah, we feel your pain. Being involved in the cult with a hundred faux-friends all the time and then finding yourself basically alone is a huge leap. Older adults who do it are lonely too, and miss their still-in family members like crazy.
I certainly understand your reasoning for wanting the shunning to stop.
But as Cappytan says, what guarantee do you have that they won't shun
you again if/when you become inactive? Please consider this carefully.
Right now your emotions have a tight grip on your thinking, but
remember that jdubs prey on your emotions so you may have a really tough
time ever leaving again. What will that do to your head now that you know TTATT?
You mentioned in your OP that your family was really close before you became jdubs, but how were things once everyone was Culticized?
