Depression is a serious medical illness; it’s not something that you make up in your head. It’s more than just feeling "down in the dumps" or "blue" for a few days. The symptoms of depression are much more severe and debilitating. Depression is characterized by feeling "down" and "low" and "hopeless" for weeks at a time. Many factors can contribute to the onset of depression, including the presence of other physical disorders, stress, poor nutrition, physical illness, personal loss and relationship difficulties. Depression isn’t always easy to detect, and people with depressive conditions do not all experience the same symptoms. It may be expressed through lack of appetite or overeating; insomnia or an unnatural desire to sleep; the abuse of drugs and alcohol; sexual promiscuity; or hostile, aggressive, or risk-taking behavior.
