These symptoms should be evaluated by your doctor. You may be suffering from anemia, a thyroid problem or even something simpler like a visual defect (you may need to wear glasses), among many other possible problems. Are you taking any prescription medications or any other drug? If so, could be the cause of your symptoms. Please ask an adult to make an appointment with your GP so that you do a physical assessment and to perform the appropriate diagnostic tests.
