Hi BJS-
Sounds like you're in a tough place right at the moment- but it also sounds like you see it as it is. Keep that in mind. The fact that you've joined here speaks volumes.
I'm 6 weeks after an op now. Yes, things have changed. With my op date looming, I remember thinking 'this'll be the last time I ejaculate'. At that time, I couldn't help but wonder if I was doing the right thing, consenting to treatment when I was symptom free, and agreeing to surgery which would impair the function of my bladder and genitals. I haven't stopped being me after the op. Continence is improving now, erectile function recovery has a longer timescale, so it's too early to mourn that one. It's not easy for me to accept change, but I deal with it each day, not always successfully. I made the right decision.. Yesterday my post op PSA test came back with an optimistic result.
Forgive me for sounding as if I'm judging your OH, but from what you've said it does sound like he has a tendency to catastrophise -I recognise it as I do it myself, although it isn't likely to go down well if you tell him I said that- I'm sure you may be able to deal with it more subtly than that. It may help you to look up 'Catastrophic Thinking' - and see if that explains how he's dealing with stuff . You might be able to quietly challenge some of those preconceptions, bit by bit. Comparing Prostate cancer to loss of sight, talking of the Abyss etc makes me think that's where he's at. He sounds very 'worst case scenario'..
I wonder how he dealt with the knowledge that he had cancer 2 years earlier, and what happened during those 2 years? I think that if it's the first major illness, then maybe it can hit harder than in someone who has known from an earlier stage that their body is fallible. With treatment looming large, what was once just passive monitoring for an uncertain future, suddenly becomes the present. The prospect of cancer, incontinence and erectile dysfunction is frightening. He has cancer- with treatment he may get rid of it. The side effects of treatment are variable.
It is often forgotten, that for all sorts of reasons not including prostate cancer, in the middle aged male population, cancer is common, incontinence is common and erectile dysfunction is common. There's an awful lot of people out there getting on with their lives with this sort of stuff. It's not the thing itself that necessarily bothers us , but the opinions we have about the thing- (I think it was Lao Tzu said that one).
Facing the operation I did entertain the thoughts 'I will develop terminal cancer, I will be totally incontinent, I will have no erectile capacity whatsoever. Having thought it, I realised how ridiculous that sounded. Having that knowledge doesn't always stop me being self pitying though.
Jillyd has mentioned the importance of support for both of you. I couldn't agree more.
..and continue to post here. You might get all sorts of nudges in the right direction to help your journey.
