It seems that you have really only two choices:
1. Disappear
2. Disassociate
I chose to disappear which I realize is not always convenient. I got tired of people coming around and asking me if I'd "given up" or "wanted to die at Armaggeddon." I got tired of elders knocking on my door at 7 AM or 9 PM. So I moved away and told no one. That's the end of that.
