What is fighter flight? my daughter was diagnosed with this at a mental health clinic

I : I think that the phrase you are seeking is "flight or fight". It represents a situation which occurs when people are very afraid or stressed. With the surge of adrenaline, people gey very keyed up and are prepared to fight or run away. This is more of a description, not a diagnosis. Best wishes.

Fight Flight: I think you mean Fight Flight Freeze response. We all have it but when that response goes on too easily or stay on too long it suggests a possible anxiety disorder. Peace and good health.

Fight or run away: Flight=run away .This is the classical response for anyone who encounters a threat. It means someone willing to stand their ground and engage in a battle or run away. It is not a diagnosis but may have been used as an explanation of her reaction to an event discussed in the visit.
