You're not alone. It's common to feel like that from time to time. However, when these feelings become so overwhelming that they interfere with your daily life, it may be time to seek medical help. You could be suffering from an anxiety disorder.
Anxiety is characterized by excessive worry about unrealistic or exaggerated life circumstances.
The symptoms of anxiety can be both physical and emotional. Physical symptoms of an anxiety disorder include shaking, muscle tension, fatigue, insomnia, breathlessness, rapid heartbeat, and sweaty hands. Emotional symptoms of an anxiety disorder include feeling on edge, excessive worry, poor concentration, irritability, and constant sadness. The best way to deal with anxiety is to talk with your family doctor. Consult your doctor if anxiety interferes with your daily activities, if you have sudden severe attacks of anxiety or fear with intense physical symptoms, or if you suffer from nightmares or flashbacks to traumatic life events.
