Grief does not follow a fixed timetable. After a death, people may experience longing, sadness, anger, guilt, numbness, disbelief, changed identity, disrupted sleep or difficulty returning to daily routines. The intensity and pattern can change over time. An online guide cannot determine whether grief is part of an expected bereavement response, prolonged grief disorder, depression, trauma, a physical health concern or another difficulty. Prolonged grief disorder is a diagnostic term used in formal classification systems, but it requires an appropriately qualified assessment. It should not be self diagnosed from the length or intensity of grief alone. A clinician may need to consider cultural and religious context, the nature of the loss, safety, trauma, previous mental health, social support, responsibilities, physical health and the effect on daily life. CBT based therapy may be considered after assessment where appropriate. It can offer a space to explore avoidance, painful reminders, self blame, changed routines, identity and the practical impact of loss. It cannot decide whether a diagnosis applies, predict recovery or replace bereavement services, specialist trauma care, a GP, psychiatric assessment or other relevant support. Urgent appropriate help is needed if you feel unable to stay safe, have thoughts of suicide or self harm, experience psychosis, a sudden marked change in mental state or acute physical symptoms.
