BMW
If she called 911, and she was coherent enough to be typing on the computer in chat, then IMHO, I would say she would be ok.
My sister works for 911 (she's an EMS and a dispatcher) and most people can't call and type at the same time if they are that sick...so I would think positive. You guys did great talking to her. It probably calmed her down a lot.
Hopefully she will come back and let you all know that she is ok. Keep trying to email her and maybe one of the Admin will know who she is.
But remember, we are not counselors here, but we do what we can. You did good.
