Angry feelings and aggressive behavior do not necessarily indicate a problem with anger. Anger is a normal and healthy emotion of an instinctive signal that something may be wrong to incite us to act quickly in negative situations. Healthy anger usually causes effective change.
Stress comes from many sources. It is highly stressful when a person delivers a wallop of emotional or physical pain to us (or someone we love). It then adds significantly more stress when we store that negativity and we don’t let it go.
