Mark ,
been reading some of this thread since it started, but never commented before due to my own personal experiance with my mums cancer. All i can say is keep fighting , do things you have always wanted to do but could never justify , and most strangley forget about it. What i'm trying to say is that it can hang over you and you sit their waiting for the worst and waste whatever time there is, where as if you get run over by a bus you dont have to live your life in fear.
From what i have read this is not you, and i may have repeated what has already been said but best of luck to you and meg.
Mike
