Depression or not? For such behaviour?

I have been having this feeling of not doing anything or procrastinating. I take new things in hand but get bored very quickly. I am getting filled with guilt, hatred, anger. More and more every day. I don't like my office work either. I don't like to discuss about politics like most people of my age used to do. At the same time i feel that i am very less knowledgeable than many others. I am always in my own world and feel as if i am alien to all of them. But, I think i just love  watching movies, eating food and sleeping but that's not enough as it doesn't give you bread and butter to survive in this world. I think i have no love and emotions for anyone else except for myself. Sometimes i also watch adult movies when doing nothing. I feel so low at times as i don't know what and where am i heading? I don't find my purpose of life even when i think of it. What kind of behaviour is this.? Is this normal? Is this a problem and if so what are the causes and remedies for such behaviour?
