Hi, I know what you are going through and maybe it is easy for me to say this but wait until you see the uro and don't jump to conclusions.
I had a psa of upto 15 at last count, was getting up some nights 9-10 times, prostate was massively enlarged, had biopsy, scans, cystoscopy, meds etc etc finally the uro diagnosed BPH and done a Turp.
I am about 5 weeks post op have good flow no bleeding and I sleep all night, still waiting for histology but I assume that was clear as they have not called me, I go for uro appointment on 28/11.
What I am trying to say is try to look to the positive, it doesn't mean you have pc just because your psa is high, bph will cause that too. I understand only too well the stress you are feeling, but don't count the losses until the race is run, easy for me to say now I am nearly home and dry, but I feel good now and that is important, in a few days maybe that will change when I see the uro, but I am thinking positive.
Try to relax, going to the uro doesn't mean pc it could be BPH.
Good luck.
Steve.
