Your first name of Tiunna has created a practical, patient, scientific nature able to concentrate on the finer details of a project or undertaking. 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. This name restricts congenial expression and association, creating much aloneness. As you keep your thoughts and feelings to yourself, this reserved quality has created misunderstandings with others because they feel left out. This name causes weaknesses in your digestive system, resulting in intestinal disorders. Sometimes moody and morbid thoughts interfere with your stability and ability to concentrate to reach your goals, especially when you are under pressure. You restrict your association to a few and usually they are people who understand your independent, quiet personality. You would find enjoyment and peace in an outdoor environment studying the flora and fauna of nature from a scientific point of view. Other health problems could affect the lungs, heart, or bronchial organs. You could express your thoughts more easily in writing than in speaking.
