A 45-year-old female presents to her primary care physician complaining of a persistent 'feeling of dread' for the past 8 months. She reports difficulty falling asleep, struggles to concentrate at work, and feels irritable and restless most days.

She denies any panic attacks or specific phobias.

A 17-year-old female is admitted to the hospital for severe malnutrition, with a BMI of 15 kg/m². She views herself as overweight despite her emaciated appearance and expresses intense fear of gaining weight. She routinely restricts her food intake to less than 500 calories per day and exercises excessively. Her menstrual periods ceased 6 months ago.

A 24-year-old male is brought to the emergency department by his family who report a 7-month history of increasingly bizarre behavior. He has been hearing voices telling him to harm himself, believes that government agents are monitoring his thoughts through his television, and speaks in a disorganized manner, making it difficult to understand him. His hygiene has deteriorated significantly, and he has stopped attending his college classes. There is no history of substance abuse or any mood episodes (depressive or manic).
