This document provides information about codependency, including what it is, where it comes from, symptoms, and how to overcome it. Codependency is an addictive relationship with other people or things where a person's self-worth depends on being in a relationship. It develops as a coping mechanism for dysfunctional families and can stem from substance abuse, mental illness, abuse or neglect. Symptoms include caretaking, low self-esteem, control issues, and responsibility for others. Overcoming codependency involves self-discovery, setting boundaries, and not basing self-worth on others through counseling or support groups. True intimacy involves each person being responsible for their own feelings.
