Reactive depression is a short-term depression caused by stress and trauma in one's life. It is characterized by symptoms such as sudden weight fluctuations, headaches, digestive problems, fatigue, emptiness, and suicidal tendencies. Unlike other forms of depression, reactive depression occurs due to a specific event or situation that has been extremely painful to bear, and it can last for a few months. Grief and reactive depression share some similar symptoms, but grief is typically a shorter-term emotional response to loss, whereas reactive depression is a clinical condition that requires therapy and medication to treat. Treatment options include supportive psychotherapy, cognitive-behavioral therapies, and medications such as SSRIs or dopamine reuptake blockers.
