Stefanie Rosa Donati,
I love that middle name, Rosa, It is my Daughter's also. You have received great advice already, mine is more of the same. Don't despair, hang in there, and tell your Dad the same. Many of us with Advanced Prostate Cancer felt the same initially. My own diagnosis has gone from dismal to encouraging to even miraculous. Stage 4 with 80% involvement, with leg, pelvis, rib mets spots. My PSA was 71 , now 7 years on this journey, my PSA is undetectable. Your Dad is fortunate to have a Daughter like you to care so so much and to be there ,to be his anchor. Looks like you have found an excellent treatment center, and that is what is needed. That and resolve, hope and vigilance.
Do me a favor, scroll up to the upper Right hand corner "Custom search" box and type in "Letters for the newly diagnosed" you will find a long thread here that is encouraging and uplifting.
Do that and also look up our friend's story, he is Todd1963, truly remarkable! https://toddseals63.blogspot.com
Prayers are with you and your family, stay with us. Keep the Faith!
