Your first name of Sidena gives you an independent, serious, reticent, and studious nature. You take seriously any responsibilities that you have—in the home, in the community, or at a job. In fact, others find it challenging to understand you as you do not reveal your innermost thoughts unless you are completely comfortable in your friendships. You are rather easily hurt or offended. You are a thoughtful, analytical person, and you know your own mind, even though you may not speak it. It is only when you are among people who understand your deeper nature that you can really be yourself. This name does not offer naturalness of expression, and as it is too serious an influence, it should be changed. An intellectual, you have a deep appreciation for art, music, literature, and all the phenomena of nature. Physically, any weaknesses in your health would centre in the heart, lungs, or bronchial organs. Worry and mental depression could be problems in your life.
