Hi Senga,
Welcome to the forum but sorry that you find yourself here. Those first few months waiting for the full diagnosis are as you say surreal and very scary. OK its not the best diagnosis BUT and it is a big but there are many treatments available for your hubby. You didn't say what your Husbands PSA score was, there are quite a few of us on here in a similar boat to yourselves we call it (The mets club).
It has been just over a year since my Hubby was diagnosed he had a PSA of 13000 we had the usual wait for scans etc and all of the worry that comes with it. He has Mets on his ribs, spine, shoulder blades and his pelvis. His kidney and lymph nodes are also affected. With this diagnosis and combined with how ill he was at that time I thought he had only weeks to live.
His last PSA test was 15.2 so his treatment for now is working very well, he is much more mobile and not in the pain that he was in. He is taking Bicalutamide and 4weekly infusions of Zometa.
There are many new drugs being developed all the time, as Bri has suggested the Tool Kit is very helpful . I see Si has also replied for you.
Stay as strong as you can, we are a very friendly bunch and for me personally the forum has been a life saver.
BFN
