I'm sorry to hear of your husbands' diagnosis. I would think one of the first stops would be Macmillian and/or a local cancer support group. Your nursing team at the hospital should be able to sign post. Our local cancer centre offered free massages etc, and although we never took that up, it was something we could have done together and my wife supported me through it.

Other than that, I'd say set small goals. The waiting is the worst but once you have some answers as to where the primary is, you can get your treatment plan and work through it - one day at a time. Don't be afraid to ask anybody for help - for small things like house hold chores to lifts to the hospital etc.

I would also perhaps set a longer term goal - something you're going to do when you are better - a holiday, a short trip, buying something you like, whatever.  :)
