What is depression? What is clinical depression?
Depression is a serious but common form of mental/mood disorder, marked by continuous feeling of sadness, a loss of interest in activities that you generally enjoy, accompanied by inability to carry out daily activities and concentrate on things, thoughts of self harm and suicide, for at least two weeks.
Depression goes by many names such as clinical depression, major depressive disorder, biological depression and the “blues”.
Depression can happen to anyone at any age. Women are more likely than men to experience depression. It is not a sign of weakness but a real medical condition with real symptoms. Once affected, you can’t escape it just by simply “pulling yourself together”.
Sadness is generally the response to one’s own life’s struggle and setbacks, but depression is different from normal sadness and it negatively affects how you think, feel, and function in daily activities.
It interferes with your ability to work, study, eat, sleep and enjoy life. With depression comes an unrelenting feeling of hopelessness, helplessness, and worthlessness with little relief, ranging from few weeks to months and years. It can lead to variety of physical and emotional complications.
Fortunately, depression can be treated with right medication, psychotherapy or both. Individuals suffering from it can make a full recovery in around six months to a year or more, if it gets diagnosed and treated properly.
