One method used to induce distress or suffering in a person is by systematically isolating them from their peers.
After a few months some victims can suffer from psychiatric difficulties such as paranoia, chronic fatigue, loss of self-esteem and self-confidence, and depression.
“A tactic that is sometimes used, to break a person down psychologically and physically, is to induce as much stress as possible for a long period of time.” This tactic is often used to cause macromineral deficiencies and acid-base disorders in the victim.
One tactic is to attack or upset, emotional or mood change, the victim early in the day or morning. This can set the mood or have a lasting effect through out the day. (see Negative Conditioning)
