Pain in the present is experienced as hurt. Pain in the past is remembered as anger. Pain in the future is perceived as anxiety. Unexpressed anger, redirected against yourself and held within, is called guilt. The depletion of energy that occurs when anger is redirected inward creates depression.
Fear is the anticipation of the pain in the future. Anger is the remembrance of pain in the past. Hostility is wanting to get even.
Anger is remembered pain, fear is anticipated pain, guilt is self-directed pain, depression is depletion of energy. Cure-return to love & joy.
