Hi DJ
Just like the others above, I'm really sorry to hear what you're going through. On this website there is huge knowledge and first-hand experience of PCA and a very useful search function. Unfortunately for me I didn't discover this website until I was the other side of peak anxiety & stress. I used google, which made my mental state 10 x worse ! I believe it's called Doom Scrolling. I'm calm now. I've been diagnosed and have a treatment plan. So will you. But the time between now and then is horrendous mentally.
My PSA was 71 and MRI PIRADS 5. Although the only way to definatively diagnose Pca is with a Biopsy, with those scores, I knew I had it. Whilst waiting for the biopsy results, I didn't go into denial. Quite the opposite. I thought I was virtually dead. I thought about my family and planned my exit from this world, making sure they'd be ok. Both of those approaches (denial / death planning) are absolutely ridiculous.
Prostate cancer is one of the slowest growing cancers. It's very treatable, and very curative if not gone too far. So whatever your diagnosis, you'll be around for many, many years to come.
I know it's pointless me saying this but I'm going to anyway.....try not to worry !
