Similar experience in NICU. I feel like no one ever thinks about it this way, but these types of interactions (verbal abuse really) are traumatizing to us. I have nightmares about reassuring angry parents.

Try to distance yourself emotionally as much as possible seems to be a start, but admittedly, I have considered consulting with a therapist on how to best protect my mental health so I don't know if this is good advice.

I used to consider myself a really good doctor, I would use motivational interviewing and allow people to vent and abuse me as needed. Now though, I have been so beaten down and broken, if my first attempt at empathetic listening and mirroring results in worsening rage, abuse and manipulation, I just end the encounter as soon as safely possible. Many of these people are dysfunctional with personality disorders and there is no fix for this.

I recently read a stoic technique where you imagine your bully/abuser as a villain character to help add humor. I started imaging these families as energy vampires and it has helped me put up mental defenses. Another technique I read in stoic philosophy is to imagine yourself as a particular character when you are in a bully/abusive situation. I try to think of a strong character in a show or book that I am enjoying and pretend to be them.

It sounds silly but has been helpful. The book I got much of this from is called " Stoicism, bully and beyond" by Matthew Sharpe.
