If she has gas, some infant simethicone could be helpful to her. The fact that she hasn’t eaten or had anything to drink in over a day is very dangerous, and that really does call for a vet visit. Do you have a rabbit savvy vet lined up in your new place? Perhaps the vet would make payment arrangements or he or she might participate in the Care Credit program, where you pay with a credit card and pay it off in installments with no interest. I think that has to be set up ahead of time, though.
Have you offered Woo all of her favorite greens and fruit, to entice her? You can dampen them too, to get some fluid in her, Do you have Critical Care to feed to her? You can also soak pellets and syringe feed her that, even mixing it with a little bit of jarred baby food or canned plain pumpkin. But it does sound like she needs to see a vet and get some fluids and whatever meds the vet deems necessary.
I hope that she will be okay and start eating.
