If you can get her to the vet that Julia suggested, please, please do so right away. If she can't go to the vet to be treated, she needs to be put to sleep. She will die if this is DKA, and it will be a horrible way to die. If all you can do is have her put to sleep, then please find it in your heart to do that for her. Of course, none of us wants that, and I'm sure you don't either. But it would be a last gift to her to let her go without pain, rather than suffering through DKA without treatment.
I am so very sorry for her, for you, and for your family,
Carl
