Your first name of Sithika has given you energy, drive, and ambition, but also an almost excessively strong-willed and independent nature. You work best alone and are happiest when expressing your many ideas creatively in an area that offers flexibility and challenge. Generally, you do not like to waste time on superficial conversation. It makes you self-sufficient and self-reliant. Therefore, if anyone interferes with your activities or offers unsolicited advice, you are inclined to react defensively and express your feelings in a blunt and, at times, caustic manner. Lavish displays of emotion tend to embarrass you, making you feel self-conscious and inadequate. You often feel you could have achieved even better results. The repression and frustration that you may experience at challenging moments in your life cause nervous indigestion and, in the worst cases, could result in ulcers and severe stomach problems. Intensity affects the senses of your head as well, whereby you could suffer with migraine headaches, sinus problems, or throat and swallowing difficulties. This name spoils relaxation and contentment, the mental qualities necessary for good health.
