The holiday season, often considered a time of joy and togetherness, can also be one of the most challenging periods for those who are grieving a loss.
Nearly 95% of people who have experienced loss report dealing with at least one symptom of physical or mental distress. Approximately 10% of them develop prolonged grief disorder, a persistent and debilitating form of grief that does not ease with time.
Often, this grief is due to the death of a loved one, but it may also be caused by the loss of a friendship, a divorce or even a job loss.
Grief affects not only mental health but also physical well-being, and it can increase the risk of heart disease, immune dysfunction and even death.
Holidays and special occasions, which often include family gatherings, traditions and reminders of whatโs missing, can amplify this pain, leaving those grieving feeling isolated and overwhelmed.
As a clinical psychologist and professor of psychiatry and neurobehavioral sciences working with cancer patients and their families, I see the profound toll grief takes on people. Iโve also experienced grief personally, both when my mother died suddenly at the age of 66 and when my father passed after a long illness at the age of 84.
Those experiences, combined with my research, have driven me to dedicate much of my career to understanding grief and its effects, and to finding effective ways to support those who are struggling with it.
Mourning vs. prolonged grief
Grief is a natural response to loss, encompassing emotional, cognitive, physical and social reactions. Common signs include sadness, withdrawal, difficulty concentrating, disrupted sleep and physical symptoms like fatigue or aches.
Grief is deeply personal, and while there is no โrightโ way to grieve, most people move through the process over time, finding a new equilibrium in their lives.
However, some people experience prolonged grief disorder, a condition newly recognized in psychiatryโs gold-standard manual, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, in 2022.
This condition is characterized by intense yearning, sorrow or preoccupation with the deceased that persists for 12 months or more, significantly impairing daily functioning. People experiencing this disorder often feel disconnected from life and unable to find joy or meaning.
Grief can have a profound effect on the brain.
Unlike nonpathological grief, prolonged grief disorder is associated with chronic activation of the brainโs stress response system, particularly in areas like the amygdala. The amygdala is a small, almond-shaped cluster of neurons in the brain that plays a key role in processing emotions, especially fear, stress and threat-related responses. Prolonged grief disorder is also linked to mental health conditions such as depression, anxiety and post-traumatic stress disorder, or PTSD.
As you support a friend or family member in their grief, itโs important to watch for signs of prolonged grief disorder because it requires targeted interventions. Research, including my ongoing studies on the use of psilocybin-assisted therapy for the treatment of grief, highlights the importance of innovative approaches to help those stuck in the cycle of prolonged grief.
If you suspect someone you love is struggling with prolonged grief, encouraging them to seek help and offering to support them in the process can be life-changing. Resources are available, from grief counseling to support groups. Organizations like the American Grief Foundation and local mental health services can provide further guidance for helping a loved one get the treatment they require.
Caring for our own grief on holidays and special occasions
Research supports several strategies for addressing grief, whether typical or prolonged:
Express emotions: Suppressing grief can exacerbate mental and physical health issues. Talking with trusted friends, journaling and joining support groups can be therapeutic.
Engage in rituals: Personal or cultural rituals, like lighting a candle, visiting a grave site or creating a memory book help integrate loss into oneโs life.
Create new traditions as a way to honor your loss: If youโre mourning a death, consider integrating your loved oneโs memory into the occasion by preparing their favorite dish, playing their favorite music or hanging an ornament in their honor.
Seek professional support: Cognitive behavioral therapy or complicated grief therapy can be effective treatments for prolonged grief disorder. Psychedelic-assisted therapy is also emerging as a promising option in clinical research.

Simply being present is one of the best ways to support a grieving loved one during the holidays.
Supporting someone as they grieve
For those grieving, holidays and special occasions like a birthday or Motherโs Day can be especially difficult. Here are some practical tips for supporting someone who is grieving during these times:
Remember that grief is not a problem to be solved, but a process to be supported.
Be present. A common fear is saying the wrong thing to someone who is grieving. Often, itโs not about saying the โperfectโ thing, but simply showing up and listening without judgment.
Acknowledge the loss. Saying โIโve been thinking about (their loved one) and how much they meant to youโ or โI want you to know that Iโve been thinking about you and the significance of what youโre experiencing right nowโ can be more comforting than avoiding the subject.
Offer practical help. Grief can be debilitating and exhausting. Assisting with tasks like cooking, shopping or child care can relieve some of the burden.
If you donโt know what to say, itโs OK to admit it. A simple โI donโt have the right words, but Iโm here for youโ can mean a great deal.
Avoid phrases like โTheyโre in a better placeโ or โEverything happens for a reason.โ While the intentions behind them are often good, these platitudes can feel dismissive.
Focus on empathy and validation. Saying โThis must be so hard for youโ or โTell me more about what youโre feelingโ opens the door to meaningful conversation and helps make space for the complex emotions that grief brings.
Respect the boundaries of your loved one whoโs grieving. Let them honor their emotions by going at their own pace.
Navigating holidays and special occasions with those who have experienced a loss can be complicated. But your presence and compassion in these moments can support their healing.
