Can't find one there? Call around to local vets and see if any of them see herps in their practice. They may do so and not advertise, or they may be able to direct you to someone who does.
As for treatment in the meantime -
Check your husbandry. Again. Temps, humidity, lighting, diet, etc. Check everything.
Has the animal been excreting? Has it been vomiting? Not doing the first and/or doing the second can indicate a gastric obstruction.
Is it possible you have a gravid female who is having difficulty giving birth?
Is it possible some toxin was ingested?
Could she have a respiratory infection?
The traditional treatment for unknown ailments is to increase temperatures to the high end of the recommended range to facilitate metabolism and to increase humidity to limit the dehydrating effects of the higher temperatures.
Pedialyte is a good choice for keeping your animal hydrated. However, giving the fluid with a syringe is tricky business. Make sure all of the fluid is actually being swallowed and you're not getting any into the lungs. Aspirated fuilds can lead to pneumonia.
You might also want to try a nutritional supplement like Nutrical -- but don't force-feed it! Try letting her lick some off your fingers or off the end of her nose.
AND GO TO THE VET!
