"Fading" from under "high control" seems an oxymoronic risk at best, and currently faders walk on eggshells and look over their shoulders for years during and after the attempt - fearful that the price of their freedom will be the destruction of their friendships and family ties.
Thanks for your words, but for the gazillionth time: Where do people get that fading is what you describe?
And please don't forget that your brainwashed still-in JW family will make your life miserable by using any scheme possible to make you stay in a relationship with them (in their terms, of course). Even the best intended, kind hearted JWs still want to have the last word.
Fading is not a graceful process. Your mindset must change, as you describe, but if you only do that you're completely ignoring the main things that makes the WT a cult.
How about in addition to all you write (which has 100% validity, in my opinion), you also educate yourself about what these groups do and how they operate? How about building a true life outside them so you have support, people you can count on, a support system, so they have no ammunition when they shun you?
Confidence can only take you so far. You need support, other people, and accept that your life and your family relationships (with those who remain JWs) will change and/or will never be the same.
If you are a person who was born in that organization, the work is harder since one has to learn a lot more about "the world". There certainly is a lot more to the story.
