Hi there ... thats the trouble with cancer , most of us feel fine, and look fine ... it creeps in while wer not looking , and hopefully they will get your mum's bloods up ... and theres a few peeps on here defying the odds ... so hold on in there ... 

My mum went suddenly with a heart attack and she phoned me one Monday morning about coming to mine on the Tuesday .. her last words were see you tomorrow love .... there was no tomorrow, she died that afternoon at 5.20 ... what I would give for just one more day, or even an hour with her ...

So I would say, hold on to every day she's there with you , hug, cry and admit your both scared ... and say all that's in your heart, leave nothing unsaid ... and listen to your mum, even though some things maybe painfull to hear ... when she's having a good day, do something fun, even things like her telling you about when she was young...  going somewhere to take her mind off things ... and on hard days, just you holding her hand will mean the world ... sometimes you don't need words ... grab every day holding her hand ...  big hug ...
