Just to comment here again and to add for the OP: if you try to "fix" and "help" this woman friend, that becomes codependecy, which is not healthy for you. That's where you try to help someone at your own expense. Trying not to react is very very difficult when the reaction is automatic and flight or fight. You can implement what is called the "grey rock" method with a narcissist, but that is encouraged when you MUST have interaction with a narcissist.
