Understanding Grief: Why Loss Changes Us

Grief is one of the most universal human experiences, yet it is also one of the most misunderstood. People often expect grief to follow a neat timeline: shock, sadness, acceptance, then “moving on.” In reality, grief is rarely linear. It can be unpredictable, physical, emotional, social, and deeply personal.

At The Lifestory Practice, we often see people questioning whether they are “grieving properly.” The evidence suggests there is no single correct way to grieve. What matters more is understanding how grief affects the mind and body, and finding ways to carry loss while still engaging in life.

What Is Grief?

Grief is the emotional, psychological, and physiological response to loss. Most commonly, this involves the death of someone important, but grief can also emerge after:

• Relationship breakdowns

• Miscarriage or infertility

• Loss of health or independence

• Trauma

• Losing a job, identity, or future plans

• Children leaving home

• Chronic illness

• Changes in family dynamics

Grief is not only about missing someone or something. It is also about adapting to a world that no longer looks the way it once did.

The Brain and Body in Grief

Research shows grief affects more than emotions. It impacts memory, concentration, sleep, appetite, stress hormones, immune functioning, and even physical pain responses.

People often describe:

• Brain fog

• Exhaustion

• Feeling emotionally numb

• Tightness in the chest

• Difficulty sleeping

• Increased anxiety

• Feeling disconnected from others

• Sudden waves of sadness triggered by memories, music, smells, or places

This is not weakness. The nervous system is responding to profound change and loss.

For some people, grief feels loud and overwhelming. For others, it feels strangely quiet or distant. Both can be normal responses.

There Is No “Right” Timeline

One of the most damaging myths around grief is the idea that people should “move on” after a certain amount of time.

Grief often changes form rather than disappearing. Early grief may feel intense and consuming. Over time, many people find the pain becomes less constant, but moments of grief can still return years later.

Birthdays, anniversaries, holidays, songs, or unexpected reminders can reactivate grief quickly. This does not mean someone is “back at square one.” It means attachment and memory remain part of being human.

Children and Grief

Children experience grief differently from adults. They may move in and out of grief quickly, appearing upset one moment and playful the next. This is often part of how children regulate overwhelming emotions.

Children may show grief through:

• Behaviour changes

• Irritability or anger

• Separation anxiety

• Difficulty concentrating

• Regression

• Physical complaints like stomach aches

• Changes in sleep or eating

Children also revisit grief developmentally. A child who loses someone at age six may understand that loss differently at age ten, fifteen, or twenty.

Open conversations, emotional safety, routine, and supportive relationships are protective factors for grieving children.

When Grief Becomes Complicated

While grief itself is not a mental illness, some people can become stuck in prolonged or highly impairing grief responses. This may include:

• Intense longing that does not ease over time

• Avoiding reminders completely

• Persistent hopelessness

• Feeling unable to re-engage in life

• Severe guilt or self-blame

• Ongoing trauma responses connected to the loss

Grief can also coexist with depression, anxiety, PTSD, or burnout.

Support may be important when grief begins significantly affecting functioning, relationships, sleep, health, or safety.

What Helps During Grief?

There is no quick fix for grief, but there are evidence-informed approaches that support adjustment and healing over time.

Helpful strategies may include:

• Maintaining basic routines around sleep, food, and movement

• Allowing emotions without judging them

• Staying connected to supportive people

• Talking about the person or loss

• Creating rituals or meaningful remembrance

• Writing, art, music, or storytelling

• Therapy to process complicated emotions or trauma linked to the loss

Importantly, healing does not mean forgetting. Many people eventually learn to integrate grief into their life story rather than erase it.

Final Thoughts

Grief changes people. It can reshape identity, relationships, priorities, and beliefs about the world. While painful, grief also reflects the depth of connection and attachment humans are capable of.

If you or someone you care about is struggling with grief, support is available. Therapy can provide a space to process emotions, understand reactions, and find ways to navigate life after loss.
