Your first name of Sidnea gives you an independent, serious, reticent, and studious nature. You express your thoughts and feelings best through writing rather than verbally. The people who mean the most to you are those who can offer you intellectual companionship. Aside from these points, this name contains many fine qualities. Your difficulty in putting your deeper thoughts and feelings into words can lead to problems in more intimate associations. You have sensitivity and appreciation for the finer and deeper things of life, the beauties of nature, music, art, and literature. You do not express yourself spontaneously when conversing with others; hence other people may often regard you as being aloof, and even unfriendly. This name has caused you to live much within yourself. Worry and mental depression could be problems in your life. Physically, any weaknesses in your health would centre in the heart, lungs, or bronchial organs.
