If you have ever experienced more than temporary worry or fear, you may have experienced anxiety. For a person with an anxiety disorder, the anxiety can get worse over time and may interfere with daily activities such as job performance, school work, or relationships. The signs of anxiety can vary between individuals. Anxiety can be sudden and startling or mild and long lasting. Therapy can help relieve the symptoms of anxiety that many people find uncomfortable, such as: sweating, nervousness, racing heartbeat, blurred vision, or increased stress about the future.
