"Control—exerting influence over one’s environment or the actions or behaviors of another person—is sometimes used excessively by those who fear the unpredictable and ambiguous, feel they need to prove themselves, or fear losing control. An incessant need for control may become overwhelming and exhausting, wreaking havoc on relationships, careers, and overall quality of life. Control is typically a reaction to the fear of losing control. People who struggle with the need to be in control often fear being at the mercy of others, and this fear may stem from traumatic events that left them feeling helpless and vulnerable. As a result, they many crave control in disproportionate and unhealthy ways. The experience of abuse or neglect, for example, can make people look for ways to regain control of their lives, and sometimes victims lash out at other people in their lives. The need for control drives people to turn to the external world in order to find things they can control. They may be compelled to micromanage and orchestrate the actions and behaviors of others, or maintain rigid rules regarding routine, diet, or cleanliness and order. For instance, people who are physically or psychologically abusive inflict pain on loved ones in the form of ridicule, isolation, restrictions, or physical or sexual assault, because they themselves are in pain, though this pain is often deeply buried and unacknowledged."
