I was in from 17 to about 29/30. I was lucky that the only member of my family in the Borg was my sister and she still kept associating with me after I left.
When I finally made the decision to fade away I remember the first night that I deliberately didn't go to a meeting. It was such a relief. I sat around, watched television, ordered out pizza and started the next day to throw out all my literature.
No more meetings, no more field service, no more trying to be accepted into a congregation where as a single sister whose family was "not in the truth" I wasn't considered to be "marriage material" for the few single brothers available (not that any of them were interesting).
It was wonderful. Congrats on getting out.
