Survival Stress - You may have heard the phrase "fight or flight" before. This is a common response to danger in all people and animals. When you are afraid that someone or something may physically hurt you, your body naturally responds with a burst of energy so that you will be better able to survive the dangerous situation (fight) or escape it all together (flight). This is survival stress.
Internal Stress - Have you ever caught yourself worrying about things you can do nothing about or worrying for no reason at all? This is internal stress and it is one of the most important kinds of stress to understand and manage. Internal stress is when people make themselves stressed. This often happens when we worry about things we can't control or put ourselves in situations we know will cause us stress. Some people become addicted to the kind of hurried, tense, lifestyle that results from being under stress. They even look for stressful situations and feel stress about things that aren't stressful.

Appraisal-focused strategies occur when the person modifies the way they think, for example: employing denial, or distancing oneself from the problem. People may alter the way they think about a problem by altering their goals and values, such as by seeing the humor in a situation: "some have suggested that humor may play a greater role as a stress moderator among women than men".[7]
People using problem-focused strategies try to deal with the cause of their problem. They do this by finding out information on the problem and learning new skills to manage the problem. Problem-focused coping is aimed at changing or eliminating the source of the stress.
Emotion-focused strategies involve releasing pent-up emotions, distracting oneself, managing hostile feelings, meditating or using systematic relaxation procedures. Emotion-focused coping "is oriented toward managing the emotions that accompany the perception of stress"
