Having a Client Say Something That Is Wounding to Me and I Go in to Fight Flight Freeze

The therapist's first job is to regulate your own nervous system. balance that concept of the therapist being authentic in the room when also being human and so I'm thinking of conversations you know where a client says something that is wounding to me, she said. How do we balance this idea of being there with the kind of caveat of like slate that we're actually humans as well yeah?
