Boundaries are an important part of healthy relationships and support overall mental health. As we set limits, we protect ourselves and others by defining what is acceptable and what is unacceptable for ourselves and our relationships. A misconception that holds many people back from setting a boundary is the notion that in so doing they might harm their relationship - yet it is often the very act of setting and maintaining boundaries that can save the relationship.

Boundaries support mental health as they:

1. Protect physical and emotional space. For example, setting a boundary to not tolerate verbal or physical abuse in our relationships can help protect us from the impact of others' harmful words and behaviors.
   
2. Promote self-care. Boundaries help us prioritize self-care by setting limits on how much time and energy we dedicate to others. By prioritizing our own needs and wellbeing, we can avoid burnout. We have to put our own oxygen mask on before we can best help others!
   
3. Enhance relationships. Clear boundaries can help us express our needs and desires, as well as understand the those of others. They help us communicate clear expectations and can help resolve conflicts. This can lead to more fulfilling and satisfying relationships.
   
4. Encourage responsibility. Setting boundaries may even encourage others to take responsibility for their own actions, rather than relying on us to meet their needs. As we release the burdens that are not ours to carry, we can minimize our own stress and feel more in control of our lives. This is a healthy form of detaching that reflects care for yourself and care for the other person.

Remember that boundaries may look different for each person - it's our job to discover what works best for ourselves. By setting and enforcing clear boundaries, we can protect our physical, emotional, and mental wellbing. With practice, setting and maintaining boundaries can become a natural and empowering aspect of our daily lives.
