The stages of grief are a framework for understanding the emotions people commonly experience after a significant loss. The most widely known version, developed by psychiatrist Elisabeth Kübler-Ross in 1969, identifies five stages: denial, anger, bargaining, depression, and acceptance. These stages aren’t a checklist or a linear path. Most people move between them unpredictably, revisit earlier stages, or experience several at once.
The Five Stages of Grief
Kübler-Ross originally outlined these stages in her book On Death and Dying, based on her work with terminally ill patients. Over time, the model has been applied to all kinds of loss, from the death of a loved one to divorce, job loss, or a serious diagnosis.
Denial is the difficulty of accepting that a loss is real. You might catch yourself speaking about a deceased loved one in the present tense, staying excessively busy to avoid confronting your feelings, or mentally treating the situation as temporary. Denial acts as an emotional buffer, giving your mind time to absorb what happened without being overwhelmed all at once.
Anger can surface in unexpected ways and often isn’t rational. You might feel furious at the person who died for leaving you, at doctors who couldn’t prevent it, or at a stranger in the grocery store who looked at you the wrong way. Anger is a natural response to feeling powerless, and it often masks deeper pain.
Bargaining tends to revolve around “if only” and “what if” thinking. Sometimes it starts before a loss fully occurs: prayers, promises, desperate attempts to negotiate a different outcome. Afterward, it shifts to replaying decisions and imagining alternate scenarios. It’s a kind of mental gymnastics, trying to undo something that can’t be undone.
Depression in grief isn’t the same as clinical depression, though it can feel similar. It shows up as a loss of hope about the future, difficulty concentrating, feeling directionless, and struggling to make even small decisions. This is the stage where the full weight of the loss tends to settle in.
Acceptance doesn’t mean feeling fine about what happened. It means learning to live with the loss, acknowledging a new reality where sorrow and joy can exist alongside one another. You’re no longer immobilized by sadness. You can hold onto grief while still experiencing good memories and maintaining some hope for the future.
The Seven-Stage Model
Grief expert David Kessler, who co-authored a book with Kübler-Ross, expanded the original five stages into seven by adding two more: shock at the beginning and testing near the end.
Shock comes first and involves a kind of numbed disbelief. It’s different from denial. Shock is the body’s immediate response to devastating news, an emotional anesthetic that prevents you from being completely overwhelmed in the first hours or days. Testing comes later, as you begin experimenting with ways to cope and rebuild. You might try new routines, take on unfamiliar responsibilities, or tentatively re-engage with social life. During testing, you may still drift in and out of other stages.
Why Grief Doesn’t Follow a Sequence
One of the biggest misconceptions about the stages model is that grief moves in order, from denial through to acceptance, like climbing a staircase. Research consistently shows this isn’t how it works. A large study tracking bereaved individuals over 27 months identified three distinct grief trajectories. About two-thirds of participants followed a resilient path, experiencing manageable symptoms from the start. Around 8% had acute symptoms that were severe for the first six months but then improved significantly between 6 and 18 months. And roughly 25% experienced chronic, elevated grief that persisted well beyond a year.
These trajectories tell a clearer story than stages alone. There’s no single “normal” timeline. Some people feel functional within weeks. Others are still deep in acute grief at the six-month mark and only begin to recover after that. Both patterns fall within the range of healthy grieving.
Worden’s Four Tasks of Mourning
An alternative to the stages model comes from psychologist William Worden, who reframed grief not as a series of emotional phases but as four active tasks. The distinction matters: stages are something that happen to you, while tasks are things you work through, at your own pace, in any order.
- Accept the reality of the loss. Moving past the instinct to minimize or deny what happened.
- Process the pain of grief. Allowing yourself to feel the full emotional weight rather than suppressing it.
- Adjust to a world without the person. Learning to handle responsibilities, roles, and daily life that the person once shared or managed.
- Find a lasting connection while re-engaging in life. Maintaining a bond with the person’s memory while building a meaningful life going forward.
Many therapists prefer this model because it gives people something to actively do rather than passively wait for an emotional stage to pass. You can revisit any task at any time, and most people do.
The Dual Process Model
Another widely used framework is the Dual Process Model, developed by researchers Margaret Stroebe and Henk Schut. It describes grief as an oscillation between two types of stress. Loss-oriented stress involves processing the death itself: looking at old photos, yearning, remembering, imagining what the person would say about something happening in your life. Restoration-oriented stress involves the practical disruptions that follow a loss: managing finances the other person handled, cooking meals, dealing with loneliness, rebuilding a social life.
Healthy grieving, in this model, means moving back and forth between the two. Some days you’re deep in the emotional work. Other days you’re focused on figuring out how to file taxes or fix the leaking faucet your partner always took care of. Neither mode is avoidance. Both are necessary. The real difficulty, for many people, is allowing themselves to do both rather than getting stuck in one.
How Grief Affects Your Body
Grief isn’t only emotional. It produces measurable changes in your body that can affect your health for months or longer. Cortisol, the body’s primary stress hormone, follows a natural rhythm throughout the day, peaking in the morning and falling at night. People experiencing intense, complicated grief show a flattened cortisol pattern, meaning the hormone stays abnormally steady instead of cycling normally. This kind of hormonal disruption is linked to cardiovascular problems and weakened immune function.
Bereaved individuals also show reduced activity in natural killer cells, which are part of the immune system’s first line of defense against infections and abnormal cells. Research dating back decades has documented what’s sometimes called the “broken heart phenomenon,” where recently bereaved people, especially surviving spouses, have significantly higher mortality rates than those who haven’t experienced a loss. People with prolonged, unresolved grief also have higher rates of high blood pressure compared to those whose grief follows a more typical course.
When Grief Becomes Prolonged Grief Disorder
Most grief, even when it’s severe, gradually eases over time. But for some people, the intensity doesn’t diminish. In 2022, the American Psychiatric Association formally recognized prolonged grief disorder as a diagnosis. For adults, the loss must have occurred at least one year ago. For children and adolescents, the threshold is six months.
A diagnosis requires at least three of the following symptoms, experienced nearly every day for at least the past month: feeling as though part of yourself has died, a persistent sense of disbelief about the death, emotional numbness, feeling that life is meaningless without the deceased, or intense loneliness and detachment from others. The grief must also last longer than would be expected given the person’s cultural, social, or religious context.
Brain imaging studies of people with prolonged grief disorder show heightened activity in areas involved in emotional processing, reward, and memory. One notable finding is increased activation in the brain’s reward center in response to reminders of the deceased, which researchers interpret as a kind of craving, similar to what happens in addiction. This may explain why some people feel compulsively drawn to revisiting memories or belongings of the person they lost, even when doing so deepens their distress.
Roughly 25% of bereaved people in one study showed elevated grief symptoms that persisted chronically over 27 months, which underscores why clinicians are cautious about diagnosing a grief disorder within the first year. Severe early grief often resolves on its own, and premature labeling could pathologize a normal, if painful, process.
