Mr Kim,
I think a lot of your problems are down to probably pointless anxiety, and as Matron said, maybe you should seek some help in that regard.
As far as your urinary difficulties are concerned, of course, you should seek the advice of your urology department as soon as possible, and put your faith in them, which in turn might relieve some of your worries mentioned earlier.
Prostate cancer at your age is about the same chance of winning the Lottery - i.e. No chance!
Best of luck.
Cheers, John.
