Anger

From Conservapedia

Anger is an unpleasant emotion usually directed at someone or something perceived as having done us undeserved harm. It is not an accidental injury which outrages us as much as intentional harm, or thoughtless negligence.

Unresolved anger can lead to resentment and/or depression. Someone feeling angry will usually have a lack of joy, a lack of judgement, a sense of inbred hate, and overall frustration.

Mental Health

Unfortunately, the young mental health field has relied almost exclusively upon the expression of anger as the primary mechanism for dealing with this powerful emotion. While expression is important at times, when solely relied on for relief from anger, it has limited value because mere words or behaviors cannot make up for the depth of resentment and bitterness that has been denied in significant relationships in childhood and adolescence. Many health professionals believe that while men feel anger more intensely than women, women are more likely to hold long-term grudges.
