We respond to external and subjective events with combinations of thoughts, feelings and behavior. Distressful events evoke reactions that are complex, but these reactions can be controlled. We control our stress response by making choices about how we think, feel, and act.
Our thoughts, feelings and actions change based on what information is available to us. However, changes in our thinking and feelings are not just based on new information. They are also based on how we choose to view that information.
We may know that a situation is dangerous and should be avoided. But we can choose to enter that situation out of a sense of duty or greater good.
