Grief is a normal process that occurs following the irreversible loss of a loved one. This process, characterized by painful experiences, varies widely and is influenced by numerous factors, including the identity of the deceased, the circumstances of their death, the individual characteristics of the bereaved, and the availability of support systems. The suddenness and violence of a loss can disrupt the normal grieving process, leading to the manifestation of traumatic symptoms. This phenomenon, referred to as “traumatic grief” in the literature, is associated with an increased risk of various psychiatric disorders, including major depression, anxiety disorders, and post-traumatic stress disorder. The death of a parent represents a profound loss for an adolescent, complicating their coping mechanisms and significantly impacting their psychological well-being. Parental loss alone is a significant risk factor for suicidal behavior in adolescents. When a parent’s death is traumatic, it can further exacerbate this risk, leading to suicidal thoughts and behaviors by disrupting the normal grief process, even in adolescents who were previously mentally healthy. This article presents the diagnosis and treatment of a 17-year-old girl who exhibited active suicidal thoughts and behaviors after her father was killed with a firearm. The objective of this case report is to explore the atypical grief symptoms that can follow traumatic losses during adolescence and to assess the effectiveness of holistic approaches that combine supportive psychotherapy with pharmacotherapy in treating such cases.
