Grief: What It Actually Is and Why You Cannot Rush It
By the OneGizmo Team | Mental Health
Almost everyone will experience significant grief at some point in their lives. The death of someone close, the end of a relationship, the loss of a career, a health diagnosis, a miscarriage — grief arises in response to any significant loss, not only death, and it does not follow a predictable schedule or resolve on a socially convenient timeline. Yet the cultural norms around grief in most Western societies are remarkably unhelpful: a brief formal acknowledgment (a funeral, a few days of compassionate leave), followed by an implicit expectation to return to function, to be "getting better," and eventually to have "moved on" — as if grief were a temporary illness rather than a fundamental human experience that changes the person who goes through it.
The science of grief has advanced considerably in recent decades, and what it shows challenges several of the most common cultural assumptions: that grief follows predictable stages, that it has a natural end point, that expressing it at length is somehow unhealthy, and that not crying is a sign of inadequate love or abnormal response. Understanding what the research actually says is not an academic exercise — for anyone in grief, or supporting someone who is, it can be the difference between an experience that is allowed to unfold naturally and one that is complicated by the additional burden of feeling it wrongly.
The Five Stages Myth
Elisabeth Kübler-Ross's 1969 model of grief — denial, anger, bargaining, depression, acceptance — is the most widely cited framework in popular understanding of grief, and one of the most misleading. Kübler-Ross developed her model from interviews with terminally ill patients facing their own deaths, not from studies of people bereaved by others' deaths. She herself later clarified that the stages were not intended as a linear sequence that everyone passes through in order, but as common emotional experiences that arise in grief — sometimes, in some people, not in any particular sequence.
Contemporary grief researchers — particularly George Bonanno at Columbia University — have found that the trajectory of grief is far more variable than any stage model suggests. Bonanno's large longitudinal studies of bereaved individuals found that approximately 35-65% of bereaved people show a pattern of resilience — maintaining relatively stable functioning throughout the grief process, with some distress but without prolonged impairment. A smaller proportion show the extended, intense grief that popular culture treats as the norm. Neither trajectory is more appropriate or more indicative of genuine love for the person lost.
What Grief Actually Does to the Brain
Grief is not purely psychological — it is a profound neurological event. Neuroscientist Mary-Frances O'Connor, who has studied the brain during acute grief using fMRI, found that regions associated with pain processing, yearning, and reward all activate when bereaved people view images of their lost loved ones. The nucleus accumbens — a key structure in the brain's reward system — shows activity during grief, suggesting that the brain is, in a sense, still "searching" for the person and experiencing the absence as a disruption of an expected reward signal. This may explain the intrusive thoughts, the moments of forgetting and sudden remembering, and the persistent yearning that characterise acute grief — the brain has not yet fully updated its model of the world to incorporate the loss.
Grief also activates the immune system, the endocrine system, and the cardiovascular system. Bereavement is associated with significantly elevated risk of cardiovascular events — the "broken heart" phenomenon has a physiological basis, documented in research showing increased mortality in bereaved spouses in the weeks following the death of a partner. Sleep, appetite, concentration, and immune function are all reliably disrupted by significant grief — which is why grief is physically exhausting in a way that can surprise people who have not experienced it before.
Complicated Grief: When the Process Gets Stuck
For approximately 10-15% of bereaved people, grief does not follow the gradual natural attenuation that most people experience. Prolonged Grief Disorder — recognised in the DSM-5-TR and ICD-11 — involves grief symptoms that remain intense and impairing for more than twelve months after the loss (six months in children), interfering significantly with daily functioning. Risk factors include sudden or traumatic death, ambivalent relationships with the deceased, loss of a child, inadequate social support, and previous history of depression or anxiety.
Prolonged Grief Disorder responds to treatment — specifically, to a targeted psychotherapy developed by Katherine Shear at Columbia that addresses the avoidance of grief-related stimuli and the unfinished psychological business of the loss. It is distinct from depression, though the two can co-occur, and requires different treatment approaches. Recognising that some grief gets genuinely stuck — and that treatment is both available and effective — is important information for anyone experiencing grief that is not gradually softening over time.
What Actually Helps
Research on what supports healthy grief points consistently toward two things: the permission to grieve without a timeline, and the presence of other people who can witness it without attempting to fix it. Bonanno's research found that the social environment of the bereaved — whether others allowed them to express grief freely, without pressure to "move on" — was among the strongest predictors of healthy grief trajectory. The desire to reassure grieving people by minimising their loss, changing the subject, or offering silver linings, however well-intentioned, often communicates that the grief is uncomfortable to witness — which adds the burden of managing others' discomfort to an already overwhelming experience.
The most helpful thing to say to someone in grief is almost always the simplest: acknowledgment. "I'm so sorry. I can't imagine how hard this is." Not solutions, not comparisons, not timelines. Presence and witness — the willingness to sit with someone in their pain without fixing it — is the most genuinely supportive thing another person can offer.
Final Thoughts
Grief does not end. It changes. The acute, destabilising pain of early loss gradually transforms — for most people, in most cases — into something that can be carried alongside a life that is again fully inhabited. The person is not forgotten, replaced, or "gotten over." They become part of the bereaved person's internal world in a different way — present in memory, in character, in the values that their relationship helped shape. Grief researcher Lois Tonkin described this not as grief shrinking but as life growing around it — the pain does not diminish as much as the rest of life expands to accommodate it. That is not moving on. It is moving forward, with the loss held, in a different relationship to it. That is what recovery from grief actually looks like.
