I don't know MamaB very well, but I do know just from reading her posts on the Dose that she has already been through so much ... I'm sorry to hear about this.
I don't either, and like you, mostly from the Dose. But when she first told us about her husband's diagnosis, I offered whatever help a stranger who knows her only in the virtual world of the internet could offer. I'm touched that she asked -- and trusted -- me to spread the word today of the terminal diagnosis, and was more than happy to do what I could.
I only hope this prayer thread, if she sees it, will bring her and her husband a measure of comfort.
