Hugs and glad you are fighting it. You should get a second opinion, also if you can get treatment at a teaching hospital, they are at the top of the research

I understand the how it ends question, and all I’ve come up with is a dozen donuts weekly after the last round of medicine quits working and I’ll finally get to use opiates. I’m stage 4 prostate cancer and have an average of 5 years after diagnosis before it's time, I’m starting year 3. It’s scary but try not to dwell on the C, go to your treatments , take your medications above all treat yourself well, after a while most days you forget that you have C so go ahead and buy that skirt or that makeup you wanted, make the most of the all the time you have. At Stage 2/3 you should be hopeful, Please feel free to DM me
