The idea of fading away sounds better though, but how can I continue doing this? By avoiding everyone/some?
Well the idea is to slowly decrease your meeting attendance and field service activity until you totally stop altogether in a year or two. When the elders start to inquire, you don't have to tell them the whole truth. Tell them you are busy with other things (ex: school, work, so on). When others start to avoid you (including the elders), this is a opportunity to see who your friends really are (this maybe a surprising time for you). Those who still talk to you and hang out with you are the ones who are a little more independent minded, and under less control of the elders. Then mention your doubts to them and let them express their doubts to you. Take it one step at a time.
Also use this time to develop non-witness friends (college campus or high school depending how old you are, various clubs, take a dance class to meet chicks, etc...). Also use this time to develop friendships with non-witness relatives.
Remember thought, YOU DON'T HAVE TO TELL THE ELDERS YOUR TRUE FEELINGS ABOUT THE ORGANIZATION, BE ELUSIVE AND DON'T ARGUE WITH THEM. Anything you tell tell them can and will be used against you in a Judicial Committee. (you should read the horror stories of those who tried to be honest with the elders)
I sure there are others on the forum who can mention some of their experiences in fading and what they did.
Good Luck
