Anxiety is an emotion characterized by feelings of tension, worried thoughts and physical changes like increased blood pressure.
Anxiety is a normal reaction to stressful situations. But in some cases, it becomes excessive and can cause sufferers to dread everyday situations.
People with anxiety disorders may often have recurring intrusive thoughts or concerns. They may avoid certain situations out of worry. They may also have physical symptoms such as sweating, trembling, dizziness or a rapid heartbeat.
