I think Ivor has a point. Anger is a sort of easy, all-purpose emotion that can substitute for any number of more subtle or ambiguous feelings that are more difficult to cop to, or more painful to experience. It's a lot simpler and less heart-rending to get angry than to feel vulnerable, ashamed, defensive, isolated, dismissed, to grieve, or to try to sort out a confusing tangle of emotions that are gnawing at you.
