Your name of Tonnisha makes you independent, self-reliant, and determined. You work best without interference, in projects that require concentration and close attention. Laughter and light pleasantries are suppressed by this name. It is challenging for you to reveal your deeper thoughts and feelings, as you tend to be self-conscious, reserved, and secretive. You are earnest and studious, but can be stubborn and fixed in your ideas and opinions. You could excel in scientific research because of your ability to concentrate and remember details, or you could be inventive along practical, mechanical lines. Difficulty in expression results in your being too positive, blunt, and candid in speech and although you are easily offended by others, you do not show it. Although you tend not to like crowds and social activities, there are occasions when you feel lonely and misunderstood. This name would cause tension in the head through troubles with either eyes, teeth, sinuses, ears, or throat or cause headaches. A very individual, independent person, you live within your own thoughts.
