Help with Daisy's cancer treatment

Daisy, my 8-year-old rabbit was recently diagnosed with lymphatic cancer. I originally thought that it was an infection due to some of her symptoms, but the vet said that her mouth was clear of infection, so it was definitely cancer. She was given at most a few months, so I'm trying to make the end as good and comfortable for her as possible. She's being given prednisone daily, and if her symptoms worsen she will have to be euthanized for her comfort (which I'm hoping will not be necessary, because it can be costly and I would rather that she be comfortable at home). Thank you for everyone who has donated so far, Daisy and I appreciate you all :)
