Sometimes it is really difficult to find out that what is wrong with you. You are sure that you have a problem but you don't know what it is. The only thought that comes into your mind again and again is that you can't do anything. You just try to find something to do and nothing attracts you anymore. Then the question comes into your mind - either it is depression or boredom?
Boredom means when you are totally free and looking here and there for something to do. People try to pass this time by watching T.V or overeating. It is an emotional stage during which people have lack of activities or don't enjoy the activities available around them. They fail to concentrate on the current activity and always try to find something new and interesting.
Whereas depression means lack of interest, energy and spark in your life. People suffering from depression make a hard shell around them and allows them to get out of neither it nor anybody get in. boredom can be controlled by so many ways but depression can not.
If you really want to come out of this confusion, you have to make a self-analysis. If you are having all the symptoms of depression like less sleep, less appetite, irritability, memory loss, loss of interest, thoughts of death and suicide etc., and then you must go for help.
Mild depression can be treated very easily but if it is severe and constant then you must seek medical help.
