Your first name of Thyessa gives you an independent, serious, reticent, and studious nature. You are very conscientious and competent in all that you do. It is only when you are among people who understand your deeper nature that you can really be yourself. The people who mean the most to you are those who can offer you intellectual companionship. 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 does not offer naturalness of expression, and as it is too serious an influence, it should be changed. This name has caused you to live much within yourself. An intellectual, you have a deep appreciation for art, music, literature, and all the phenomena of nature. It has created separateness from others and loneliness in your life. Worry and mental depression could be problems in your life.
