Why Does Losing a Best Friend Hurt So Much? Friendships and family relationships are among the most significant connections in our lives, yet the pain of losing a close friend or experiencing family estrangement is often overlooked. While society acknowledges the emotional devastation of romantic breakups, friendship and family breakups can be just as heartbreaking—sometimes even more so. This raises the question: why does losing a best friend hurt so much?

The Lifespan of Friendships and Family Bonds

Studies show that the average person will have around 396 friendships over a lifetime, but only about 33 of those will be considered close relationships. Even more striking is the fact that we tend to lose nearly half of our close friendships every seven years due to life changes, misunderstandings, or simply growing apart. Family relationships, though often more permanent, can also experience strain and breakage due to conflicts, mismatched values, or toxic dynamics. The sociology of relationships highlights that our social circles are fluid, yet losing a best friend or becoming estranged from family often feels like losing a part of ourselves.

The Psychology Behind Friendship and Family Breakups

Unlike romantic relationships, friendships and family relationships often lack defined closure. When a romantic relationship ends, there is usually an explicit conversation or societal expectation that marks its conclusion. Friendships and family ties, however, may fade away or break suddenly without a clear ending, leaving one or both parties confused and grieving.

Why does losing a best friend hurt so much? The answer lies in the deep emotional connections that friendships and family provide. They serve as pillars of support, sources of validation, and integral parts of our identity. When these relationships dissolve, it can trigger grief, similar to mourning the death of a loved one.

Emotional Impact of Losing a Best Friend or Family Member

Losing a best friend or experiencing family estrangement isn’t just an emotional setback—it can have psychological and physiological effects, including:

  • Increased stress levels
  • Higher risk of anxiety and depression
  • Feelings of rejection and loneliness
  • Lower self-esteem due to the loss of validation

Breakups in friendships and family relationships often feel isolating because society does not always recognize their significance. Unlike romantic breakups, which are met with sympathy and support, losing a best friend or cutting ties with a toxic family member may be dismissed as “just moving on.” However, research suggests that emotional pain from relationship loss activates the same brain regions as physical pain, reinforcing the idea that social disconnection is a deeply distressing experience.

Why Friendships and Family Relationships End

Relationships can end for a variety of reasons, including:

  • Life Transitions: Moving, career changes, marriage, and parenthood can shift priorities and create distance.
  • Mismatched Values: As individuals grow, their outlooks on life may evolve, leading to ideological differences.
  • One-Sided Effort: If one person is consistently investing more in the relationship, resentment can build.
  • Betrayal or Breach of Trust: Dishonesty, gossip, or lack of support can erode even the strongest bonds.
  • Toxicity or Emotional Drain: If a relationship becomes more harmful than beneficial, walking away may be necessary for mental well-being.
  • Lack of Boundaries: Unhealthy boundaries in friendships or family dynamics can cause tension and eventual separation.

Regardless of the reason, why does losing a best friend hurt so much? Because friendships and family relationships form a key part of our support system, identity, and sense of belonging.

Setting Boundaries to Maintain Healthy Relationships

One of the most effective ways to prevent friendship and family breakups is to establish and maintain healthy boundaries. Boundaries help define what is acceptable and what is not in relationships, preventing resentment and misunderstandings.

  • Communicate Clearly: Express needs and expectations in a direct but respectful way.
  • Recognize Red Flags: If a relationship consistently drains you emotionally, it may be time to re-evaluate its place in your life.
  • Prioritize Mental Health: If interactions with a friend or family member cause stress and anxiety, setting limits or stepping back may be necessary.
  • Don’t Feel Guilty About Saying No: You are not obligated to maintain relationships that are detrimental to your well-being.

  • Allow Yourself to Grieve – Accept that losing a best friend or family member is a loss, and feeling sad is completely valid.
  • Reflect Without Blame – Instead of focusing on who was at fault, acknowledge what led to the end of the relationship.
  • Seek Closure – If possible, have an honest conversation with the person to find resolution.
  • Journal or Write a Letter – Expressing your thoughts on paper (even if you don’t send it) can help process emotions.
  • Lean on Other Support Systems – Turn to family, remaining friends, or a therapist for comfort.
  • Remove Reminders If Necessary – If certain memories make it harder to move on, it may help to set boundaries with social media or remove reminders.
  • Open Yourself to New Relationships – Over time, building new connections can help restore your social well-being.

Moving Forward After Losing a Best Friend or Family Member

Although the pain of losing a best friend or becoming estranged from family can be overwhelming, it also presents an opportunity for growth and self-discovery. Relationships, like all aspects of life, evolve over time, and while some may end, others will form. The key is to cherish the meaningful connections we make along the way while understanding that loss is a natural part of life.

So, why does losing a best friend hurt so much? Because friendships and family relationships are fundamental to our happiness, identity, and emotional well-being. Acknowledging this pain and allowing yourself to heal is essential in moving forward and making room for new, fulfilling relationships.
