Grief Was Never Supposed to Move in Five Neat Stages
Denial, anger, bargaining, depression, acceptance, in that order, is not actually how grief researchers think it works anymore, and it never described bereaved people to begin with.
Somewhere along the way, most people picked up the same idea about grief: you move through denial, then anger, then bargaining, then depression, and eventually you land on acceptance, in that order, like checkpoints on a map. When grief does not cooperate with that order, and it almost never does, a lot of people quietly conclude they are doing it wrong. They are not. The model itself was built for something else entirely.
The five stages come from psychiatrist Elisabeth Kubler-Ross's 1969 book On Death and Dying, and here is the detail that gets lost almost every time the model gets repeated: she developed it by observing terminally ill patients coming to terms with their own approaching death, not people grieving the loss of someone else. It was only decades later, in a book published shortly before her death, that the framework got extended to bereavement at all. Facing your own mortality and mourning someone else's death are related experiences, but they are not the same one, and a model built for the first was never rigorously tested as a description of the second.
Grief researchers have moved considerably past strict stage models since then. The Dual Process Model, developed by researchers Margaret Stroebe and Henk Schut, describes something closer to oscillation than progression: bereaved people move back and forth between loss-oriented coping, directly confronting the pain and the absence, and restoration-oriented coping, engaging with practical life and building a future, often within the same day, sometimes within the same hour. Neither direction is more advanced or more correct than the other. The movement between them is the actual mechanism of adjusting to a loss, not a detour from it.

A second major shift came from researchers Dennis Klass, Phyllis Silverman, and Steven Nickman, whose work on what they called continuing bonds directly challenged an older assumption, dating back to Freud, that healthy grieving required fully detaching from the person who died. Their research found the opposite: maintaining an ongoing connection to someone who has died, through memory, through ritual, through talking to them, through carrying their values forward, is normal and, for most people, genuinely adaptive rather than a sign of being stuck. The old goal of grief work was closure. The newer, better supported understanding is that grief does not need to close to be handled well.
The five stages were not even the only stage-like model to follow Kubler-Ross, which is worth knowing if you have ever felt boxed in by hers specifically. William Worden proposed four tasks of mourning rather than stages, framing grief as active work rather than something that simply happens to you. Theresa Rando offered a six-part model sometimes summarized as the six Rs. Neither replaced Kubler-Ross's cultural dominance, but their existence alone makes a useful point: even among grief researchers, there was never consensus on one correct roadmap, only competing attempts to describe something that keeps resisting a single tidy structure.
None of this means the five stages are useless. Denial, anger, bargaining, depression, and something like acceptance are all real, common experiences that show up somewhere in a lot of people's grief, and the language gave a generation of people a starting vocabulary for something almost nobody talked about openly before. The mistake was never in naming those experiences. It was in arranging them into a sequence and implying that skipping one, doubling back to an earlier one, or never quite reaching the last one meant something had gone wrong.
If you are grieving and your experience does not look like a tidy progression, if you feel like you have already made peace with a loss only to be flattened by it again eight months later, that is not regression. Grief researchers increasingly describe this as simply how loss actually works: it resurfaces, it ebbs, it comes back sharper on anniversaries and quieter in between, for years, sometimes for good, without that ongoing presence meaning you have failed to grieve correctly. There was never a correct order to begin with.
