Grief

Grief is a natural, multifaceted response to loss, particularly the loss of someone to whom a person has formed a strong emotional bond. It encompasses a range of emotional, cognitive, behavioral, and physiological reactions. Psychologically, grief involves processes of mourning, adaptation to loss, and eventual reorganization of life without the deceased or lost object. It is not a uniform process but varies depending on cultural, interpersonal, and individual factors (1). Grief is a complex, normative emotional response to loss, most commonly the death of a significant other. It involves a range of affective, cognitive, behavioral, and somatic symptoms, and is shaped by cultural, social, and individual factors. Grief is not a pathological condition in itself, but a natural part of the human experience (2).
