I have to admit, when I just saw the thread title, and not the OP's name, I did an eye roll and thought, "Not this again." I was not expecting this.
What a remarkable story and what a struggle it must have been for him. As someone who is suffering depression among other things, I just can't imagine keep up working while having huge delusional episodes that can most likely make even the simplest chores in life incredibly difficult. What a guy!
Also it's a relief for a long time fan that everyone can now stop second guessing why the sudden change happened. It all happened for very serious reasons and it is completely understandable.
