I have no opinion on this thread, or at least I am in no position to advise David, or anyone on what they should do in this regard.
I just want to make an observation about Zen's first point.
How could we say that depression, or whatever term, we use to describe 2 years of hell here on earth, does not influence our decisions for the future ? I am not depressed, at least not clinically diagnosed, and I must say my current state of mind certainly influences my decisions for the future.
My life is good. In my current state of mind, as much as I would hate the idea of having to go on HT, I would most likely do whatever I could to maintain my current status as long as I could. I would endure hot flashes, big nipples, no hair, whatever to hold my grandkids, love my wife, run my business, etc.
Had I endured 1/10th of what David has gone through, I can guarantee you my thinking about tomorrow would be different.
