It can put things in perspective at times. All you can do is either fight it the best you can or accept the things you can't change. I know a few people with cancer, and have overcome it only for it to come back again.
So, the best I can do is offer my unflinching support.
Yes, cancer fkn sucks and my thoughts also go out to my mother-in-law and I hope for the best result for her. It's the pain and suffering my wife is going through that I struggle to deal with effectively though. She isn't demanding of course, that's not her style, but I want to support her the best I can and I am struggling to understand how.
Thanks for your reply though, greatly appreciated.
