Your first name of Derrer has given you a quick, analytical mind. Competitive sports or challenging outdoor activities could bring you pleasure and relief from pent-up frustrations. You feel happy as long as headway is being made, but as soon as you are obstructed or your individuality and freedom of action are restricted, you experience an intense nervous reaction. You are happy and in good spirits as long as headway is being made, but as soon as you feel obstructed or your individuality and freedom of action are curtailed, you experience an intense nervous reaction in your solar plexus. Moods of depression often result as well as outbursts of temper, caustic remarks, or a belligerent attitude towards everyone, especially those closest to you. At the best of times, you are not naturally disposed to be companionable and sociable, as diplomacy and finding the right words for the situation do not come easily to you. Any criticism from others causes you to retaliate cuttingly in self-defense. Your self-sufficient and self-reliant nature gave you the urge to leave home early in life to be free from parental restraint, and to establish your independence and freedom from tradition. Ailments could also centre in the head causing headaches, sinus problems, or defective eyesight, hearing, or teeth. The effect of the nervous tension can appear in childhood as stuttering.
