Fantastic!!! Enjoy your freedom.
No, WT will never go away. It may decline but will not go away.
When the Elders come a knockin, just tell them that you are fine and if you need them, you know where to find them. You don't owe them anything.
If you have family in, WT will never go away. There will always be those reminders that the indoctrination runs deep.
Just remember, they are stuck in a cult, you are free!!! Enjoy!!!
