Boundaries

The Psychology of Self-Protection

Boundaries are not walls; they are the perimeter of your psychological safety. In neuroscience terms, a boundary is the distinction between “Self” and “Other.” Without clear boundaries, the brain cannot distinguish between your emotions and someone else’s, leading to enmeshment and emotional contagion.

The Cost of Porous Boundaries

When you fail to set boundaries, you engage in People Pleasing—a fawn response.

• The Threat: The brain perceives saying “No” as a risk of social rejection (which the primitive brain equates to death).

• The Toll: To avoid this risk, you suppress your own needs, creating a state of chronic high cortisol. You are essentially setting yourself on fire to keep others warm, leading to inevitable burnout and resentment.

Architecture of a “No”

Setting a boundary is an Executive Function skill.

• Cognitive Reframing: Shift the frame from “I am being mean” to “I am protecting my resources.”

• The Pause: Buy yourself time. “I need to check my calendar” allows you to step out of the immediate social pressure, engage your Prefrontal Cortex, and make a decision aligned with your capacity, not your fear.
