CAUSES OF LONELINESS: I guess it's because of lack of friends who really care about you, who share the same minds with you and have some values that can add to you, rather than reducing you. If one has such friends, one will not feel insecure to visit them or chat up with them and kill off the loneliness, and they too will not feel lazy or insecure or selfish to chat up with one or visit one when it's right to do so. A true Christian who cannot find a true Christian like him to make friend will be forced or tempted to be in wrong companies or go where he is not supposed to go or engage in immoral sexual activities to kill off the loneliness. At times, you withdraw from chating up with certain people, because they too don't do same. They always expect you to chat up first, and then you fall back on loneliness.
