Boundaries are important for several reasons. First, they help you maintain your own identity, integrity, and self-care. By setting boundaries, you acknowledge your own needs, preferences, and limits, and you avoid compromising them for the sake of pleasing others or avoiding conflict. You also protect yourself from taking on too much responsibility, feeling guilty, or being manipulated by others. Second, they help you build trust, respect, and rapport with your peers. By setting boundaries, you communicate clearly and honestly what you can and cannot do, and what you expect and accept from others. You also show that you value yourself and others as individuals, and that you respect each other's differences and choices. Third, they help you enhance your peer support skills and effectiveness. By setting boundaries, you create a safe and supportive environment where you and your peers can share, learn, and grow together. You also avoid role confusion, role conflict, or role overload, and you focus on your peer support goals and objectives.
