Poor sweetheart. I swear the human race makes me sick. You should be very careful not to allow her to gorge on food or water as her system could really get messed up. Bloat from wolfing down large quantities all at once could be fatal. Tiny meals all day is the safest way to help build her up again. It would be great if she went to the vets for a day or two of intravenous fluids to help nourish that bony thin body. Please keep us updated, and I'm so happy you saved her life, and so sad her mate died.
