Complicated Grief: When Grief Doesn't Seem to Heal

For most people, grief — while devastating — shifts over time. The acute, consuming pain of early loss gradually becomes something more livable: grief that is present but no longer paralyzing. For some, however, this transition doesn't happen. Months pass, then a year, then more — and the grief remains as raw and unrelenting as it was at the beginning.

This is complicated grief, also called prolonged grief disorder (PGD) — a recognized clinical condition that affects an estimated 7–10% of bereaved people. Understanding it is the first step to getting help.

What Is Complicated Grief?

Complicated grief is not simply "grieving a lot" or "grieving too long." It is a distinct pattern of grief that has not responded to the natural healing processes that most bereaved people experience. It was officially recognized as a diagnosable condition (Prolonged Grief Disorder) in the DSM-5-TR in 2022.

The core features are intense longing for the person who died and difficulty accepting the reality of the death — persisting at a clinically significant level for at least 12 months after the loss (6 months for children).

Signs of Complicated Grief

You may be experiencing complicated grief if you recognize several of these patterns:

• Persistent, intense longing for the deceased that hasn't diminished significantly over time
• Difficulty accepting the death — the reality of it still doesn't feel real or possible
• Feeling that life is meaningless without the person who died
• Bitterness or anger about the loss that has not eased
• Difficulty trusting others or forming new connections since the loss
• Feeling emotionally numb or detached from life, as if watching from a distance
• Avoiding reminders of the loss OR being unable to stop seeking them out
• Feeling that a part of you died with the person
• Inability to engage in life activities that you valued before the loss

The key distinction from normal grief is duration, severity, and functional impairment. If these symptoms are present and significantly interfering with your life more than a year after the loss, it is worth seeking a professional evaluation.

Who Is at Risk?

Certain factors are associated with higher risk of developing complicated grief:

• Sudden, unexpected, or traumatic death (accident, suicide, homicide)
• Death of a child (at any age)
• The loss of a spouse or life partner
• A relationship that was very close, dependent, or ambivalent
• History of previous loss, trauma, or mental health difficulties
• Lack of adequate social support
• Being the caregiver for the person who died

None of these factors means complicated grief is inevitable — and the absence of them doesn't protect against it.

How Complicated Grief Differs from Depression and PTSD

Complicated grief shares features with both depression and PTSD, but it is distinct from both:

• Depression involves pervasive sadness and hopelessness not specifically tied to thoughts of the deceased. Complicated grief is specifically organized around the loss.
• PTSD is centered on fear and intrusive re-experiencing of a traumatic event. Complicated grief is centered on longing and separation distress.

Complicated grief can co-occur with depression and PTSD — and often does. Treatment needs to address all co-occurring conditions.

Effective Treatment: Complicated Grief Treatment (CGT)

Complicated grief responds well to specialized treatment — and standard depression therapy alone is typically less effective. The most evidence-based intervention is Complicated Grief Treatment (CGT), developed by Dr. Katherine Shear at Columbia University.

CGT is a structured, 16-session protocol that combines:

• Psychoeducation about grief and complicated grief
• Motivational enhancement to engage in the treatment
• Imaginal revisiting of the death (to process the loss)
• Situational revisiting (facing avoided reminders)
• Work on aspirations and life goals

Multiple randomized controlled trials have shown CGT to be significantly more effective than standard interpersonal therapy for complicated grief. It is available through trained therapists, and training is expanding across the US.

Other Helpful Approaches

• Grief-focused CBT — cognitive behavioral approaches adapted for grief
• EMDR — particularly useful when the death was traumatic
• Medication — antidepressants may help with co-occurring depression; research on PGD-specific medication is ongoing
• Peer support groups — specific groups for complicated grief experiences (e.g., suicide loss, child loss) can reduce isolation

What If Someone I Love Has Complicated Grief?

Supporting someone with complicated grief requires patience and gentleness. Avoid pressure to "move on" or timeframes for recovery. Instead:

• Acknowledge their pain without minimizing it
• Encourage — gently, over time — professional support
• Stay present and consistent without expectations of progress
• Take care of your own wellbeing too
