There is no doubt that you are suffering from 'depression'. Depression is a state of mind which today's scientific world is trying to prove as clinical disease. But nobody really knows what it is and how it happens.I believe psychology is still far beyond the reach of science caz some people have started to think psychiatry as a pseudoscience not a science.So, there is no any perfect cure for depression unless he understands his own problem and cures himself and tries to accomodate in the real world. There is always a reason ( a situation that a person tries to overcome/ something a person missed but he does/doesn't know) behind a depression, but every depressed man may not know what the reason is. Some bitter truth about depression..(based on experience) 1) An undepressed person never understands a depressed person. 2) Suggesting and trying to help him might make him more depressed. 3) A depressed person develops another depression thinking he has 'depression' 4) A depressed person never accepts any suggestion the way it is supposed to be. 5) A depression may not be a feeeling of inferiority but a feeling of extreme superiority that makes him worried and deppressed about his own superiority-being feeling .(Psychoneurosis) If anybody feels one of the above statements are exactly true...I am sure he has some depression too..caz others think its bullshit and never tries to understand... Dude, why dont you find your problem and solve yourself? If you think it is impossible, or you dont have any problem and its a matter of superiority/inferiority, just accept it!!remember- ACCEPTING MIND IS A SUPERIOR MIND!! and one more thing...thinking only is not the way of solution of every problem. Mind only does everything based on our 5 senses.Who knows there could be some more and we are lacking it!!
