Anxiety is a normal response to stressful situations. It is a feeling of unease, such as worry or fear, that can be mild or severe. However, for some people, anxiety can become a disorder that affects their everyday life. Anxiety disorder is a common mental health condition that affects millions of people worldwide.

Anxiety disorders can take many different forms. Some people experience generalized anxiety disorder (GAD), which is characterized by persistent, excessive worry about a variety of things. Others experience panic disorder, which is marked by sudden, intense episodes of fear or panic. Phobias are another form of anxiety disorder, which involve intense fear or avoidance of specific objects or situations. Obsessive-compulsive disorder (OCD) is also an anxiety disorder, which is characterized by obsessive thoughts and compulsive behaviours.

Symptoms of anxiety disorder can vary but may include feelings of restlessness, irritability, fatigue, difficulty concentrating, muscle tension, and sleep disturbances. People with an anxiety disorder may also experience physical symptoms such as sweating, trembling, and heart palpitations.
