the best thing for you to do is post this letter on the internet for other curious people to read. As far as the elders, they will simply scan through it looking for some official line where you say that you're no longer a JW or whatever. Other than that, they're just toss it into the trash, either because (1) they are too stupid to understand all the words you used or (2) they are too lazy to read something as real and geniune as this letter that you have obviously poured your heart into.
The funny thing about what's written in the Watchtower and Awakes, even recent ones, is that no devout JW really gives two sh*ts about what's written. There is an underlying arrangement set in stone, and you either follow it, or you're out. It's kind of like a Hallmark card, they are nice to get and the funny little quip/inspirational poem/motivational statement may be quite comforting and make you feel all warm and fuzzy, but 20 seconds after putting down the card, you forget all about it. Same way with the WT literature. It's almost written from a dog's perspective. A dog doesn't remember the past nor cares for the future; it live in the NOW.
That's probably why they print those despicable magazines every other day. I read The Count of Monte Cristo like 5 years ago. It was such an awesome work of literature that I still remember the plot and details to this day. And that is the fundemental difference between good literature and Watchtower sh*t.
I have no idea what i'm talking about. Good letter.
