“ At its heart, Codependency is a set of behaviors developed to manage the anxiety that comes when our primary attachments are formed with people who are inconsistent or unavailable in their response to us. Our anxiety-based responses to life can include over-reactivity, image management, unrealistic beliefs about our limits, and attempts to control the reality of others to the point where we lose our boundaries, self-esteem, and even our own reality. Ultimately, Codependency is a chronic stress disease, which can devastate our immune system and lead to systemic and even life-threatening illness. ”
