Complicated Grief: When Mourning Gets Stuck

Three years after her husband died, she still set two plates for dinner most nights, out of habit, or maybe out of something closer to refusal. Grief was supposed to soften with time, everyone kept telling her that, gently, with good intentions. Hers hadn’t moved, not meaningfully, not in a long while, and somewhere along the way she’d quietly stopped telling people how bad it still was, sensing that the ordinary sympathy available for grief has a shelf life most people aren’t told about in advance. What she was experiencing has a specific clinical name: complicated grief, now formally recognized as prolonged grief disorder.

How Complicated Grief Differs From Grief Itself

Grief researcher Katherine Shear’s extensive work at Columbia University helped establish complicated grief as a distinct, treatable condition, separate from the natural, if painful, process of ordinary bereavement. Ordinary grief, however intense initially, generally shows a trajectory over time, waves of pain that gradually become less frequent and less overwhelming, alongside a person’s return to engagement with life. Complicated grief is marked by that trajectory stalling: intense yearning and preoccupation with the deceased that doesn’t ease meaningfully over an extended period, often a year or more, alongside persistent difficulty accepting the loss and re-engaging with ordinary life and relationships.

Now a Formal Diagnosis

The condition, under the name prolonged grief disorder, was formally added to the DSM-5-TR, reflecting a growing clinical consensus that this isn’t simply grief that takes longer, it’s a distinct pattern that, left unaddressed, tends to persist rather than resolve on its own the way ordinary grief typically does. Formal recognition matters because it opens the door to specific treatment protocols, rather than complicated grief being treated as either standard depression, which responds to different interventions, or simply a personal failure to grieve properly.

What Distinguishes It in Practice

A few signals tend to distinguish complicated grief from grief that’s simply taking its own time: a persistent sense of disbelief about the loss well beyond the initial period; intense avoidance of reminders of the loss, or conversely an inability to engage with anything except reminders of it; a marked sense that life is meaningless or that a part of oneself died along with the person; and significant, sustained impairment in daily functioning, relationships, or work that shows no real trajectory of improvement over an extended period.

Complicated Grief Therapy: A Specific, Tested Protocol

Shear and colleagues developed and tested a specific treatment protocol, complicated grief therapy, which combines elements of grief-focused work with techniques adapted from trauma treatment, including revisiting the story of the loss in a structured, supported way and working directly with avoidance patterns that have kept the grief frozen in place. Clinical trials comparing this protocol to standard depression treatment for people specifically diagnosed with complicated grief have found it produces meaningfully better outcomes, suggesting complicated grief genuinely benefits from treatment tailored to its specific mechanism rather than general depression treatment alone.

Why This Matters

Without a name for what’s happening, complicated grief is often mistaken, by the person experiencing it and by people around them, for either a personal failure to grieve correctly or a permanent, unchangeable state. Neither is accurate. It’s a recognized, treatable condition with a specific evidence-based treatment behind it, which means the years-long stuckness many people quietly assume is just how their grief is going to be doesn’t have to be the actual ceiling.

What to Actually Do

If a significant loss from a year or more ago still feels essentially unchanged, not softened, not integrated, just as raw and disruptive as it was early on, that’s worth raising specifically with a therapist, using the term complicated grief or prolonged grief disorder, rather than assuming it’s simply how you grieve or waiting for it to resolve on its own.

This Week

If this describes your own experience, or someone you know, naming it explicitly, to yourself, to a doctor, to a therapist, is the actual first step. A grief that’s been quietly labeled "just how I am now" for years is often a grief that’s never actually been named for what it is.
