She should be okay. Watch her, have water available, and you're going to basically stay up with her all night while she is like that until she comes back around. As soon/if she becomes unresponsive (which she probably won't) bring her to an emergency vet, do you have one in your area?

Put some water on your finger, she if she wants any; she probably couldn't get water on her own. Just comfort her, hold her, etc.
