We all need boundaries. They help us develop and sustain healthy, reciprocal relationships. Without boundaries, we're easily harmed, drained, and may become resentful or fearful in relationships. Fear of being hurt may lead us to build walls. But walls isolate, and prevent us from developing meaningful connections. When we cultivate self-awareness, we can better identify and assert boundaries so that we can be vulnerable enough to connect, but confident enough to protect our physical and emotional integrity.
