What Is Anxiety?

Anxiety affects your thoughts, emotions, physical sensations, and behaviour. You might worry constantly, feel restless or on edge, have trouble concentrating, or avoid situations that make you anxious. Physical symptoms can include a racing heart, sweating, trembling, or feeling short of breath.

Anxiety disorders are different from normal anxiety in several ways: they're more intense, last longer, and significantly impact your daily life. They can affect your work, school, relationships, and overall quality of life.

The good news is that anxiety disorders are highly treatable. With proper treatment, most people with anxiety disorders can learn to manage their symptoms and live full, productive lives.
