Sorry Molly isn't still feeling well.
As far as the litter box goes, can you make a small platform in front of the box so she doesn't have to step as high?
I used a couple pieces of 2 inch thick rigid foam insulation board to create height to get into the litter boxes when my angel cats were getting old and couldn't quite step over the lower front of the boxes. I just covered them with a washable puppy pee pad/mat to hide the pink foam color and provide traction for the cats.
You may have to make a series of different heights to make it easier for Molly to get in the box. I am still using one piece of the 2 inch foam board as one of my newer cats has short legs and it makes it easier for him to enter and leave the box.
