Hello Steve,
I'm sorry to hear you're feeling down.Is your PSA currently 2? Why do you believe that you may die? Excuse my naiivity.
Which health condition gives you more worry? For myself, I worry about my heart disease.
With all your problems, I admire your determination to even enter a running race! I can't run 10 yards! The only exercise I can take, is to go out walking, or use my exercise bike.
Keep pestering your oncologist and health professionals. If they give you hormone therapy once more, wouldn't that be a good thing; besides the side effects of course. And don't think that you may not be cured - have you actually been told that?
Frank.
