Don't say a word. Don't meet with the Elders. If you don't say anything, they can't use anything against you. We have told NOBODY in our family how we really feel. No one knows and we aren't telling. If you need to vent, vent on here or keep a journal.
If you don't want to do their little required tasks, just tell them you are busy or are not feeling well. Nothing more.
You don't owe anyone an explanation. People, in general, are nosy (especially JW's). If they are going to talk about you, they will have to make up something. Not only does this drive em crazy, it is kinda fun to watch them try so hard to extract info, only to find you're not playing into their hands.
