It is sometimes difficult to distinguish between pervasive anxiety and depression, because people who are depressed may also be anxious and agitated and may even have anxiety attacks. Moreover, people with anxiety disorders may become demoralized and depressed as their illness interferes with their ability to live a normal and happy life. There are, however, some major differences. People with anxiety disorders generally do not suffer the same degrees of lethargy, as do those with depression. Anxious people are more apt to have trouble falling asleep, rather than waking up early, which is a hallmark of depression. Anxiety does not impair a person's ability to enjoy things or to be cheered up, as depression often does.
