Codependency in relationships refers to a dysfunctional pattern where individuals prioritize the needs of others at the expense of their own well-being. It often involves an excessive reliance on the validation and approval of others for a sense of self-worth. 

Recognizing codependency involves identifying signs such as an inability to set boundaries, an overwhelming fear of rejection, and an intense need for external validation. Healing from codependency requires self-awareness and a commitment to personal growth. This process involves setting and enforcing healthy boundaries, developing a stronger sense of self, and fostering independence. 

Seeking support through therapy, self-help resources, and building a support network can be instrumental in breaking free from codependent patterns, allowing individuals to cultivate healthier, more balanced relationships and a more fulfilling sense of self.
