Yes as the exams approve near we tend to predict what's going to happen. What you are feeling is anxiety. As u are a student let me give u an equation how anxiety works. Anxiety = uncertanity x powerlessness. The quoins can be uncertain but u are not powerless. If you are preparing even a small bit your anxiety will reduce. Defocus from uncertainty and focus on power strategy. In ur case the power is preparation the Monet u start it anxiety will reduce.

Hello there. I can understand your concern. May be because of fear of exams and lack of sleep. Just eat well and sleep well you will be fine. Consult a psychiatrist in person for further evaluation and management. Best regards. Dr. Anil Kumar Jain. Bangalore.
