There's not a lot you can do until you can get her to a vet for proper care and medication. I wouldn't soak her because that will just create additional stress, but you could bump the temps and humidity. Other than that, don't handle her at all until you can get her to a vet.

You can try to call the vet number now to see if they have an emergency contact, and if you do talk to the vet see if you can defer payment. Many vets will work out payment plans.

Good luck!
