I had T3b and Gleason 9 and PSA=19 and was told that it was not a good idea to have an operation in the sense of cutting. But I did have Brachytherapy and now I seem to be clear, although still on check ups. So that's an initial big zap of radiation and then regular radiation for about 5 weeks, followed by the dreaded Zoladex for two years. Its a good treatment: about 80-90 % survival after 5 years (read the papers, being an inquisitive old f).
"Castration" is only temporary: once Zoladex is stopped, so does its depressive effect, and testosterone and sex drive comes back, with sort of not bad dry orgasms. Still waiting for the erectile disfunction to stop (double negative). But, can't have everything.
I think all us heroes have copying strategies. I have my own internal fear/anger/sadness chart. My trick is simple to acknowledge which I am are feeling. I got sad mostly, a bit less recently.
