Tells her whole life story right away is typically a red flag for me.

Maybe something is going on with her you don't know about and her mind was occupied with it. You could try asking her if everything is OK. Simple question, she might tell you, or she might freak out, or maybe say nothing as she sinks deeper into it.
Sometimes you need to make a big wave to counter the one coming at chew.
