Your first name of Seuwelyn has created a practical, patient, scientific nature able to concentrate on the finer details of a project or undertaking. You do not like to be interrupted or hurried once you start a project. Sometimes moody and morbid thoughts interfere with your stability and ability to concentrate to reach your goals, especially when you are under pressure. You desire to be understood, but your self-consciousness makes it challenging for you to be relaxed and friendly. You would function best in settled conditions where you are not called upon to meet and mix too closely with others, but are able to work on your own. You enjoy learning from discussions, but express your deeper thoughts and feelings better through writing. You are not impulsive, for you like to plan and to think ideas through before acting. This name causes weaknesses in your digestive system, resulting in intestinal disorders. You seldom experience the peace of mind that comes with composed thinking and emotional control. Other health problems could affect the lungs, heart, or bronchial organs.
