Thanks everyone for your thoughts.

She has been sick with bronchitis for almost 2 weeks. I'm not sure if she's diabetic or not but my dad said he blood pressure was really high (or low?? I forget) She had just had a normal cold and was getting treated for it, but this happened.

I think they kept her overnight so they could get her rehydrated and feeling a bit better. I'll let you guys know more when I know more... I still don't know the whole story.
