Anxiety can be an unpleasant emotional state ranging from mild unease to
intense fear. There can be a feeling of impending doom, although there is no obvious
threat, and it has certain physical and psychological symptoms.
A certain amount of anxiety is normal and serves as a motivator and helps us improve our performance. Anxiety becomes a problem, however, when it starts to inhibit thought and disrupts behavior and normal life activities.
Some clues that anxiety has gotten out of hand are excessive worry that lasts a period of at least 6 months, restlessness, being easily fatigued, difficulty concentrating, irritability, muscle tension, disturbed sleep, changes in appetite, diarrhea, ulcers, acid reflux and/or nausea.
Remember that from time to time we may all experience these symptoms, but anxiety needs to be treated when the intensity, duration or frequency of the anxiety and worry is far out of proportion to the actual likelihood or impact of the feared events.
