Answer:
positive self-talk
Explanation:
According to my research on studies conducted by various psychologists, I can say that based on the information provided within the question the pain strategy that she would be using is called positive self-talk. This term refers to a statement that an individual says to themselves during a negative event or situation in order to bring out hope, joy, optimism, or even will power in that situation. In this scenario, "Pain is weakness leaving the body" is a positive self-talk phrase aimed at making the individual continue a painful activity hoping it's making them stronger (less weak).
