This is the best sand I've found...

If you have something to use as substrate (6 to 8" deep) now that will hold a tunnel/hole I would set it up right now...add a couple of low branches so she has a place to sit but not so tall that she can climb out and put her in there now. I would lay a long linear light across the top of the bin to give her light and pray she starts digging. If she does do t let her see you watching her and let her be.
If is doesn't work then she needs to see a vet asap/,yesterday".
