The first kind of loneliness is temporary.This is the most common type.It usually disappears quickly and does not require any special attention.The second kind，situation—for example，family problem，the death of a loved one，or moving to a new place.Although this kind of loneliness can cause physical problems，such as headaches and sleeplessness，it usually does not last for more than a year.

　　The third kind of loneliness is the most severe.Unlike the second type，chronic(the opposite of “temporary”)usually lasts more than two years and has no specific cause.People who experience habitual loneliness have problems socializing and becoming close to others.Unfortunately，many chronically lonely people think there is little or nothing they can do to improve their condition.

　　Psychologists agree that one important factor in loneliness is a person's social contacts，for example，friends，family members，co­workers，etc.We depend on various people for different reasons.For instance，our families give us emotional support，our parents and teachers give us guidance，and our friends share similar interests and activities.However，psychologists have found that，though lonely people may have many social contacts，they sometimes feel they should have more.They question their popularity.

　　Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness as heart disease，while temporary and situational loneliness can be a sad，and sometimes dangerous condition.
