I have stage 4 metastatic prostate cancer too. My wife asks me all the time - "Where is your head". It s obvious when I am upset because I become quiet and closed off in my own head. I've been fighting this now for 27 months. I have PTSD from the bone pain I suffering in the beginning. I never want to experience that again and it scares me more than dying. Most days I do fine. What is fine when you are facing stage 4 metastatic prostate cancer? I guess it is accepting that this is a new normal for my life. I feel good that I fought very hard in the beginning by taking radiation to my back and ribs, ADT, Darolutamide, followed by 10 chemotherapy treatments. I as able to endure more treatment then most men can handle and it has payed off. But, there was a price to pay. 10 chemo treatments has taken a very long time to recover. Radiation the worst. It is hard when I get a simple infection, lay me out. But I keep going. I get up and go to work everyday to provide for my family. I live as normal a life as I can. I accept I am not 6"1 238lbs of muscle anymore. I am thinner with les muscle. But, I can work, I can play, I have my family and I have Jesus. I get my strength through Jesus. But, there are some days I do get down, but I keep going and believing I will have a full life despite this horrible disease. Find a purpose in life. Find or restart a hobby. As for me, I used to be a pretty good Jazz Guitar player. I'm trying to work my way back. Puzzles are also helpful too. God Bless everyone. Praying for your healing.
