Hi Kirsten,
I'm so sorry for your loss. That is very very sad and of course terribly hard for you to deal with.

As far as the eating, people have given me the advice to just not think about it, just eat automatically and to think of it as 'my job' in order to stay healthy for my family. I know that seems like lame advice - it's such a hard struggle, but I wish you the best.
take care of yourself,
