I'm so sorry to hear you got that news. As you meet with doctors have someone go with you to takes notes. It helps you focus on your questions. I still refer back to mine. There is a lot of information out there, but don't let it take you down rabbit holes.
This site does have a good support group system. I'm not too far ahead of you. I am 56 and was diagnosed stage 4 metastatic prostate cancer at end of May this year. I finished radiation last week and on ADT now. Last psa test went from 68 to 6.9. I too am still learning my new normal. Keep fighting as we are hear for you.
