A "nervous breakdown" is a term often used to describe a period of intense mental distress or emotional instability. It is not a formal medical diagnosis but typically refers to an individual's inability to cope with stress, leading to symptoms such as anxiety, depression, and overwhelming fatigue. Factors contributing to a nervous breakdown can include work pressure, personal loss, or significant life changes. During a nervous breakdown, individuals may experience difficulty functioning in daily life, affecting their relationships and responsibilities. Treatment options often involve therapy, medication, and lifestyle changes to manage stress and improve mental health. Seeking help from a mental health professional is crucial for recovery.
