Co-dependency is where a person is manipulated or controlled by another person. The codependent puts little or no value on their own needs, and concentrates on the needs of the other. Codependency can happen in any type of relationship whether it is an intimate personal relationship, with a member of the family, a friend or a work colleague.
A co-dependent will display many characteristics including low self-esteem, repressed anger and a lack of assertiveness. Their main objective is to please and to help someone else. This makes needy people attractive to them, someone they can take care of. They feel a constant need to prove their worth, believing due to their low self-esteem that they are not good enough. They feel constantly anxious and can be obsessive to the extremes. They have a habit of spying and checking up on people, always trying to catch them out. They centre their lives around their relationship, and will even stay in an abusive relationship rather than be on their own. They believe they are incapable of taking care of themselves.
Co-dependency can lead to many other problems and health issues. They can become withdrawn, violent, develop eating disorders, become an alcoholic or addicted to drugs.
