2. Sleep Problems
Sleep disruptions or trouble falling asleep are another important sign of an anxiety disorder.
According to one study, both sleep laboratory and epidemiological analysis shows that insomnia is one of the most common signs of psychiatric disorders, particularly Generalized Anxiety Disorder.
In fact, according to researchers and psychologists, anxiety disorder is likely the most common cause of insomnia.
3. Health Phobia
Health phobia—or hypochondriasis—might actually be the sign of an anxiety disorder. If you are constantly worried about your health and frequently diagnosing yourself with new symptoms and diseases you might actually have a treatable anxiety disorder.
Take a look at recent research published in the British Journal of Psychiatry that discusses the connection between anxiety disorder and health phobia[2].
