Acute anxieties, also known as angsts (6 letters), are intense feelings of fear, worry, and unease that can be caused by a variety of situations. These anxieties can be short-term or long-term and can range from mild to severe. They can be triggered by a specific event or situation, or they can be more general and persistent. Acute anxieties can have a significant impact on a person's life, leading to physical and mental health issues.
