Everyone gets down from time to time, but feelings of sadness that last two or more weeks may be a sign of depression. Depression causes persistent feelings of sadness and loss of interest. It affects how you feel, think, and behave. It significantly impacts normal day-to-day activities and can lead to serious emotional and physical problems.
Depression affects more than 16 million American adults each year, yet only about a third of those suffering from severe depression seek treatment from a mental health professional. Too many people resist treatment because they believe depression isn’t serious, that they can treat it themselves or don’t consider it a medical illness.
