Loneliness is a feeling of emptiness or hollowness inside you. You feel isolated or separated from the world, cut off from those you would like to have contact with. There are different kinds of loneliness and different degrees of loneliness. You might experience loneliness as a vague feeling that something is not right, a kind of minor emptiness. Or you might feel loneliness as a very intense deprivation and deep pain. One type of loneliness might be related to missing a specific individual because they have died or because they are so far away. Another type might be involve feeling alone and out of contact with people because you are actually physically isolated from people like you might be if you work alone on the night shift or are off alone in a part of a building where people seldom go. You might even feel emotionally isolated when you are surrounded by people but are having difficulty reaching out to them
