How long does grief last?
There is no set timeline. For most people, the most intense grief eases between 6 months and 2 years after the death, according to the National Cancer Institute. It doesn't move in a straight line, and waves can come years later. Grief that stays intense and disabling for a year or more may be prolonged grief disorder, which can be treated.

- An estimated 4% to 15% of bereaved adults have persistent grief symptoms (American Psychiatric Association, as of 2026).
- Prolonged grief disorder can be diagnosed when the death was at least a year ago for an adult, or at least 6 months ago for a child or teenager (American Psychiatric Association, DSM-5-TR, as of 2026).

How long does grief last after the death of a parent?
Most people adjust over time. The National Cancer Institute says that for most bereaved people, symptoms lessen between 6 months and 2 years after the loss. It also says there is no typical grief response, and recovery time varies from person to person.
The NCI lists what affects how long it takes: your relationship with the person who died, how much support you have, and your coping skills and mental health history. Your culture, religion and social and financial situation matter too. So two people grieving the same parent can take very different amounts of time.
NIA says that for most people the intense pain lessens with time, with good days and bad days along the way. The first time you laugh at a joke or enjoy a visit with a friend, you may feel guilty or surprised. That is common.
Why does grief come in waves?
Grief often comes in short bursts. The NCI calls them grief bursts or pangs: periods of very intense distress that last around 20 to 30 minutes.
Reminders of the person often set them off, such as holidays, the anniversary of the death, or giving away their things. At other times they seem to come for no reason.
In normal grief, these waves come less often and feel less severe as time passes. A wave a year or two later doesn't mean you are back at the start.
Is grief brain fog normal?
Yes. Grief is physical as well as emotional. NIA says people who are grieving often have trouble sleeping, little interest in food, problems with concentration and a hard time making decisions. The NCI adds fatigue and loss of interest in life.
Dreams about the person, or a moment when you think you see or hear them, are also part of normal grief, according to the NCI.
- Write things down. Keep one list of what needs doing and who you talked to.
- Put off big decisions you don't have to make now.
- Eat regular meals, even small ones, and go to bed at a regular time. NIA says grief can be hard on your health.
- Go easy on alcohol. NIA warns that drinking too much can put your health at risk.
- See your doctor if you haven't in a while, and tell them what's happened.
Is it grief or depression?
They overlap, but they aren't the same. The NCI describes some differences. In grief, painful feelings come and go instead of staying constant.
Grief tends to feel like emptiness, while being unable to feel any pleasure is more typical of depression. Grieving people usually keep their sense of self-worth. When they think about death, the thoughts tend to be about joining the person who died.
Depression can happen alongside grief. If low mood, worthlessness or hopelessness stay with you most of the time, talk to a doctor.
What is prolonged grief disorder?
Prolonged grief disorder is a diagnosis for grief that stays intense and disabling. It is listed in the DSM-5-TR, the manual U.S. psychiatrists use to diagnose mental health conditions. The American Psychiatric Association says an estimated 4% to 15% of bereaved adults have persistent symptoms.
A clinician checks three things. First, the death was at least a year ago for an adult, or at least 6 months ago for a child or teenager. Second, the grief has lasted longer than your culture or religion would expect, and it causes serious distress or trouble with daily life.
Third, for at least the last month, nearly every day, you have had at least 3 of these:
- Feeling as if part of you has died
- A strong sense of disbelief about the death
- Avoiding reminders that the person is dead
- Intense emotional pain, such as anger, bitterness or sorrow, about the death
- Trouble getting back to friends, interests or plans for the future
- Feeling emotionally numb
- Feeling that life is meaningless
- Intense loneliness, or feeling detached from other people
What helps, and when should you get help?
Many people find it helps to talk with others who knew the person. NIA suggests support groups, which hospitals, senior centers, faith groups and funeral homes can point you to.
Hospices offer grief support to families, and NIA says you can ask for it even if hospice wasn't used. Some counselors charge on a sliding scale based on income.
Prolonged grief disorder can be treated. The APA says cognitive behavioral approaches, including prolonged grief therapy, have been shown to reduce symptoms. Online programs where people write notes to the person who died have helped too, and our unsent letter tool is a private place to try that.
