Codependency is a pattern of behavior in which a person excessively relies on others for their sense of self-worth and identity. It often involves putting other people's needs before one's own, sacrificing personal boundaries and values, and enabling unhealthy behaviors. Overcoming codependency involves recognizing and changing these behaviors by setting boundaries, practicing self-care, and building self-esteem. This may also involve seeking professional help from a therapist or support group to gain insight and develop healthier coping mechanisms. With commitment and effort, it's possible to break the cycle of codependency and build healthy, fulfilling relationships.
