Psychology says people who keep feeling the pain of losing someone may not be choosing to stay stuck

Sometimes grief does not feel like a straight line. A person may seem fine for weeks and then hear a familiar song, smell a particular perfume, visit an old place or discover an old photograph and suddenly feel the loss as intensely as before. They may even wonder why the pain keeps returning when they desperately want to move forward. Psychology suggests that recurring grief is not necessarily a sign that someone is refusing to let go. Attachment, memory, emotional conditioning, rumination and the continuing-bonds process can all influence how loss is experienced. For some people, reminders can reactivate an emotional response that had become quieter, while for others, repeatedly thinking about the person may represent an attempt to maintain a meaningful psychological connection.

Psychology Says Grief Does Not Follow a Straight Timeline

The popular idea that grief moves neatly through predictable stages has been challenged by modern grief research. Psychologists Margaret Stroebe and Henk Schut developed the Dual Process Model of Coping with Bereavement, which describes grieving as an oscillation between loss-oriented experiences and restoration-oriented activities.

In practical terms, someone can spend a day thinking intensely about the person they lost and the next day concentrate on work, friends or ordinary responsibilities. Neither response necessarily means they are “doing grief wrong.”


This explains why someone can believe they have moved forward and still experience an unexpectedly painful day months or years later. Grief can return because adaptation involves repeatedly moving between confronting the loss and engaging with life.

Psychology Says Attachment Can Make Loss Feel Like It Is Happening Again

Attachment theory, associated with psychologist John Bowlby, provides another explanation.

Close relationships become part of our psychological world. When someone important dies, the brain does not instantly erase the person's role from memory simply because we understand intellectually that they are gone.

Research on continuing bonds suggests that maintaining an internal connection with a deceased person can sometimes be a normal part of adaptation rather than evidence that someone has failed to move on. Stroebe, Schut and Kathrin Boerner argue that attachment theory can help explain why people differ in how continuing bonds affect bereavement.

For example, someone may still talk silently to a deceased parent, keep their belongings or imagine what advice that person would have given. The relationship has changed form, but its psychological representation remains.

Psychology Says Memories Can Reactivate the Pain Without Permission

Grief is also closely connected with associative memory. A photograph, song, location, smell or ordinary object can become associated with a person during years of shared experiences. Later, encountering that cue can automatically activate memories connected to the relationship.

Imagine someone who always drank tea with a parent in the evening. Years after the parent's death, making that same tea may suddenly produce an intense emotional reaction.

The person did not consciously decide to remember. The environmental cue activated an established network of memories. This helps explain why grief can appear suddenly even when someone has been functioning well.

Psychology Says Repeated Thinking Can Sometimes Intensify Emotional Pain

Another mechanism is rumination, a pattern of repetitive, often passive thinking about distress and its causes or consequences.

Psychologist Susan Nolen-Hoeksema extensively studied rumination and found that repetitive negative thinking can prolong and intensify emotional distress in some circumstances.

Grief-related thinking is not automatically rumination. Remembering someone, looking through photographs or thinking about what they meant to you can be meaningful. The distinction is whether the thinking becomes repetitive, difficult to control and increasingly distressing.


For example, repeatedly asking, “Why did this happen? What if I had called them? What could I have done differently?” can create a mental loop that keeps emotional pain active.

Psychology Says Some People Keep Revisiting the Loss Because Their Brain Is Trying to Make Sense of It

A major loss can disrupt a person's assumptions about the world. Psychologists Ronnie Janoff-Bulman and others have studied how traumatic or life-changing events can challenge people's fundamental beliefs about safety, predictability and meaning.

Bereavement can similarly create a gap between what someone expected and what actually happened. The mind may repeatedly revisit memories while trying to construct a coherent understanding of the loss.

This is particularly apparent after sudden or unexpected deaths, where there may be unanswered questions or a powerful sense of disbelief.

Research on prolonged grief shows that intrusive thoughts and images, longing and difficulty accepting the loss can become prominent symptoms for some bereaved people.

Psychology Says Continuing to Feel Pain Does Not Mean You Loved Someone “Too Much”

One of the most important findings from modern grief research is that there is no universal timetable for emotional recovery.

Someone can laugh, work, travel and build new relationships while still missing the person they lost. A continuing bond can coexist with adaptation.

However, there is an important distinction between recurring grief and Prolonged Grief Disorder (PGD). The American Psychiatric Association's DSM-5-TR recognizes PGD as a clinical disorder involving persistent, intense yearning or preoccupation with the deceased accompanied by significant impairment. For adults, the diagnostic framework requires the death to have occurred at least 12 months earlier.

That does not mean someone who still cries or misses a loved one after a year has PGD. The crucial issue is the severity, persistence and impact on daily functioning.

Psychology Says Healing Does Not Always Mean Forgetting

The psychological goal of grief is not necessarily to erase the person from your mind. Sometimes adaptation means learning that the person is absent while allowing the relationship's memories, values and meaning to remain.

A person can eventually experience joy without betraying the person they lost. They can build a future without abandoning the past.

So if the pain occasionally returns despite a genuine desire to move forward, psychology suggests that this does not automatically mean you are stuck. Sometimes the mind is simply reminding you that an important attachment existed.

FAQs

Why does grief suddenly come back after I thought I had moved on?

Memories can be activated by familiar places, smells, songs, photographs or anniversaries. These cues can bring back emotional responses associated with the person even after someone has been functioning well.

Why do I keep thinking about someone I lost even when I don't want to?

Strong attachments create enduring mental representations. Unwanted thoughts can also be reinforced by rumination, reminders and attempts to make sense of the loss.
