According to Robert Weiss, there are two types of loneliness. In social isolation, a person feels deprived of a network of friends or relatives; in emotional isolation, a person feels deprived of a single, intense relationship. These two kinds of loneliness share a common emotional core, and there is some debate about how clearly they can be distinguished (Russell et al., 1984). Either one can be momentary or a long-lasting characteristic of the individual.
Emotional Isolation often strikes the war veterans at the same time as social anxiety and depression. Like social anxiety, emotional isolation and depression are characterized by the deliberating pattern of social interaction.
Social anxiety comes in two varieties. The state of social anxiety is a momentary experience that flares up at a certain time or in a certain place, and then passes. The trait of social anxiety is more enduring: a characteristic of certain individuals that persists over time and across situations. For those chronically afflicted, their anxiety locks them into increasingly unpleasant social interactions. Such individuals tend to reject other people, perhaps because they fear being rejected themselves. They are withdrawn and ineffective in social interactions, perhaps because they perceive negative reactions even where there are none. In fact, however, other people often do react negatively to interactions with socially anxious individuals.
Feelings of social discomfort can arise from a number of sources. They can be a learned reaction of to unpleasant encounters, as social problems in the past contribute to social anxiety about the future. That is why, it has often been seen that war veterans usually suffer anxiety.
Depression is a psychological disorder characterized by negative moods, low esteem, pessimism, lack of initiative, and slowed thought process. Although there are numerous influences on depression, social psychologists have paid particular attention to the role of cognitive factors.
Researchers believed that depression is caused due to the exposure to uncontrollable, aversive stimulation. They proposed that organisms exposed to an uncontrollable event learn something- namely that control is not possible. Faced with this knowledge, they stop trying to exert control even in a different situation. That is the case of war veterans. They have seen too much cruelty, huge toll of human lives, immense loss of property and resources, heinous and inhuman war crimes; and above-all the aftermath-miseries, diseases and moral decay, over which they have no control whatsoever. This feeling of
