Your name of Sinia gives you a strong urge for independence. Investigating and studying various aspects of nature, for example, as an astronomer or naturalist, appeal to your desire to seek an understanding of life. Neither sentimental nor idealistic, you take life as it comes and learn as you go. You stick stubbornly to your ideas or decisions, in spite of any appeals or advice; you are not willing to accept a compromise. Even though you are aware of what is required, it is difficult to convey emotional sentiments such as sympathy or compliments. Although you realize perfectly well what is expected of you, you are unable to find the right words, and hence you end up saying something inappropriate in a candid way. You have known misunderstandings and a tendency to jealousy and moods of depression. Once you get an idea, you forge ahead, despite obstacles, until you reach the end of your project. The health weaknesses due to the influence of this name could cause you to suffer either with headaches, weak eyes, sinus problems, lung and bronchial disorders such as asthma or emphysema, or a heart condition. There is originality and depth of thought contained in this name, particularly along practical and mathematical lines.
