@MarkBerks...
As you mentioned 'man-up', let's expand on it...
There comes a point at which 'STFU, deal with it' becomes a genuinely caring and worthwhile suggestion rather than uncaring cruel dismissal.
And hey, guess what?
Such a point as been reached, and your 'digging deeper, within' will be helpful to you.
Whatever 'external empathy and sympathy' is sought and available is relatively minor in comparison with what you personally 'need' and are almost certainly able (with appropriate mindset and effort) to do.
Right now, the facts are clear: you have pain, which may be symptomatic of PCa.
Further supposition is: you may actually have PCa.
If you don't, or do, we can again call on fact: if you don't, that's one worry less. If you do, then it's either relatively minor or relatively significant.
Returning again to conjecture: if such PCa is relatively minor, you'll probably not be too troubled by it. If it's sufficiently relatively significant it'll kill you.
So, 'them's the facts, them's the guesses'.
Beyond what I've already suggested, my advice is 'remember that it could always be worse, and be grateful that it's not'.
[Yesterday at my GP surgery (for the hormone-block jab I'd forgotten to get last week - yes, so unbothered am I by my PCa, that I forgot to do the thing that's helping keep me alive and in relative good health), I clumsily quipped on this with: 'Yes, I could be living in Netwon Abbot.' [My apologies to those so-located, for my unfair dismissal of your locale.]
