Cancelled Dinner Plans

Z just called to tell me she just wants to be alone. She's so tired. I have no doubt. What I wanted to do, and will still do if given permission, is to take food to her. I would prepare well balanced, organic, vegetarian meals for her and deliver them. I could cook a couple of days meals and deliver them every other day. But she says she has cottage cheese and an avocado. That's a snack to me, not a meal. She ate her well balanced and hearty vegetarian three square meals a day at the hospital with relish. How am I going to get her to eat? I have gone over her dietary restrictions and don't find anything in the food plan the hospital sent home with her that would be a problem for me. I make myself hungry just planning imaginary meals for her. Will she let me feed her? She's always loved my cooking or so she says, and so it seems, when she's here eating. I will have to figure this out and fast.
