Feeling sad and helpless

Daisy, I am so sorry that your dear friend has had this diagnosis. And it seems that you are her dearest friend and will have to find the strength to be with her on this journey.
I don't know what your joint interests are, or if she is well enough to be active. But if you can do things together, go out to places, read, sew, whatever, that might be something.
When my DH was dying in the hospice last October, I read to him for hours which did comfort him. And it stopped me from crying. You're not there yet with your friend, but it might help at the end.

Daisy I am so sorry to hear this. I can’t add to what others have so wisely said but I agree she probably wants to live her life as normally as possible and maybe your job is to help with that and perhaps share a joke or two to cheer her?

Thank you everyone for your words of encouragement. It is just so hard when I think of what she is going through with a lovely husband who is not able to support her because he doesn't understand what is going on. When they got back from seeing the consultant he was worrying about a kitchen drawer that was sticking. She is determined to carry on as normal for as long as possible and we have plans to go out to lunch which is one of our favourite things. She is waiting to hear what happens next - they are talking of chemo but whether it is palliative or not I'm not sure. I am praying that she is given years rather than months.
