Trauma refers to an emotional, psychological, or physical response to an event or series of events that are overwhelming, distressing, or harmful. It can occur as a result of one-time incidents, such as a car accident or natural disaster, or prolonged exposure to harmful conditions, such as chronic abuse or neglect. The effects of trauma can vary widely from person to person. Trauma can deeply affect a person’s mental health, relationships, and ability to function in everyday life.
