Psychological stress is a normal response to events that threaten or upset your body system in some way. Whenever you sense danger, whether real or imagined, the defense mechanism of the body kicks into high gear in an automatic and rapid process referred to as fight or flight or freeze reaction.
Coping occurs as a response to psychological stress with the sole purpose of maintaining emotional and mental wellbeing. Life consists of both negative and positive events such as loss of a job, divorce, marriage, a new job, moving, and many others. These events can constitute life stressors; hence the need for all of us to learn coping skills to help adapt and move on smoothly from one stressor to another.
The thoughts, behaviors, and emotions you use to adapt to the changes occurring in your life are your coping strategies.
