Which condition is defined as an uneasiness or worry about future events?

The condition defined as an uneasiness or worry about future events is anxiety. Anxiety encompasses a range of experiences, including nervousness, apprehension, and concern regarding potential threats or stressors that may occur in the future. It is characterized by excessive fear or worry that can interfere with daily activities and is often accompanied by physical symptoms such as increased heart rate and sweating.

In contrast, a panic attack typically involves sudden and intense episodes of fear or discomfort that peak within minutes and can lead to physical symptoms like chest pain or a feeling of choking. Phobia refers specifically to an irrational fear of a particular object or situation that leads to avoidance behavior. Depression is characterized by a persistent feeling of sadness or loss of interest that affects functioning and does not primarily focus on worry about future events. Thus, anxiety is the most appropriate term for the condition related to uneasiness or worry, as it captures the essence of being preoccupied with what may happen ahead.
