Feelings include persistent sadness, worry, irritability or empty mood, a loss of interest or pleasure in ordinary things and activities, guilt, hopelessness, or worthlessness, and a lack of concentration or ability to make decisions. Depression can produce certain physical symptoms such as a disruption in appetite and sleep. For example, a significant increase in sleep or ongoing restless sleep. Other physical effects include low energy or fatigue or unexplained pains in different body areas. These changes may negatively impact everyday activities including school, work, relationships and eating habits.
Social withdrawal can also occur as a result of depression.
In addition, depression can manifest negative thought patterns such as putting oneself down and feeling worthless. Sometimes these negative thoughts have such a significant spiraling effect that the hopelessness leads to thoughts of suicide. However depression is not a weakness, rather it is a disorder that has solutions. Furthermore, some people are more susceptible to being depressed if they have close relatives that have suffered from depression science depression can be related to family history. But many times people attribute their depression to themselves rather than all of these different factior that may impact its development.
