Alive,
I don't have much time to answer as thoroughly as I'd like, but your story is very touching and it mirrors ours so closely that I had to say something. I just wanted to assure you that although it didn't seem possible at first, if a mid 50's couple like Mrs. Zahut and I can survive the same upheaval and disillusionment you've described in your post, so can you. If you are like us, the more distance from the watchtower organization you put behind you, the more the depression, anxiety and mental distress you've been experiencing, will fade. Once the scales fall from your eyes, continuing to force yourself to continue in the same manner as before, is terribly damaging and we did so for way too long.
it's like 'cake' - they said. All the ingredients make cake, but apart from cake they are something else, eggs, flour etc.
Your Pioneer friends explanation is just one example of the insane "red herring" style reasoning you are expected to sit by quietly and swallow as a JW. They use these illustrations that at first glance appear to be reasonable but a second later when they sink in, they make you want to tear your hair out and cause you to question everything else they say as well.
Comparing the baking or "putting together" of ingredients to make an ordinary cake, to the deconstruction or "separating out" of "sacred" whole blood, is a ludicrous comparison.
In one process you are using separate ingredients to build something ordinary, in the other, you are taking an already existing "sacred" substance and taking it completely apart. These are two very different processes, never mind the fact that If you took whole cake and tried to separate out it's ingredients, you'd have a pile of useless cake crumbs.
Anyway, I'm glad you've told us a little of your back story (there's always more isn't there ?) and I hope doing so has brought you a measure of relief . -Pete
