A boundary is a limit defining you in relationship to someone or to something. Boundaries can be physical such as a step away from someone and help you to create more space between you and others where you might feel perhaps safer. They can be emotional, and these help you to identify emotions, feelings, needs and requirements that acknowledge your difference to others. Without boundaries we lose ourselves. Setting and maintaining boundaries might not come naturally and you might feel guilty. But healthy boundaries contribute to your self-care, healthy relationships and greater control over your life.
