Depression
Common symptoms of depression include feelings of sadness, anxiety, and irritability. People with depression may experience chronic fatigue, concentration issues, and sleep problems.
These symptoms can be vague and overlap with other conditions such as bipolar disorder, anxiety disorders, and post-traumatic stress disorder.
“Diagnosing depression requires a complete history and physical exam,” says Richard Shadick, PhD, associate adjunct professor of psychology and director of the counseling center at Pace University in New York City.
