I saw this movie some time ago, but unfortunately don't know the title nor actors in it. It's about a woman who is diagnosed with cancer (I think it's cancer) and has a few months left to live. She moves in into this huge apartment but has no stuff. Meaning no furniture, no wardrobe, no dishes, nothing! Then she starts buying things, I think towels and a mattress which are important for her for some reason (this stuck in my mind). I remember a scene when she orders pizza and make the guy leave it in front of her door. She force him to leave, arguing that she can't open the door because she has no clothes... I'm not sure, but I think they (pizza-guy and her) become friends.
This is as much as I remember. I know it isn't really much, but any help would be wonderful!
P.S. I apologize for any misspelling or bad grammar!
