I think you will get a lot of help and support on here.
My partner was diagnosed a couple of years with prostate cancer, and also was put on hormone treatment, which two years down the line he's still on. There's so many roads to travel supporting a loved one with this cancer. He had radiotherapy for 7 weeks, and thankfully it has staved off the cancer - for a while. I personally found MacMillan nurses invaluable, also if there's a Maggies Centre near the hospital, it's a comforting environment to be in.
My advice is you need to talk, if not to each other, then reach out to friends. Oh Lindylou I feel so much for you as I've travelled the same road, and still travel it. There will be so much support from others who may be able to express themselves better than I can at the moment. Please PM me if you'd feel like to chat...
