Depression is more than just a feeling of overwhelming sadness or grief. Instead, the condition is diagnosed when sadness, loss of interest in relationships and activities and even certain physical symptoms persist chronically for long periods of time. Often, individuals experiencing depression have no explanation for their feelings, nor are they capable of ‘coming around’ or ‘getting a grip’ on reality.
The severity of depression varies from person to person, as do the types of symptoms. Examples of common signs of depression include:
sadness, emptiness, trouble concentrating or focusing, suicidal feelings or thoughts, chronic fatigue, changes in appetite, sleeping disorders.
Often, depression is the result of an event or other health condition that caused a chemical change within the brain tissues. Some people are genetically pre-disposed to develop depression, while others develop the condition due to certain stressful activities or responsibilities. Major life events, such as a death or divorce, can cause depression, as can certain lifestyle habits, such as drinking alcohol or taking certain drugs and medications.
