Although, I knew what I wanted to say, at the important moment I could not open my mouth. I was really stressed and this "stress" led me to my failure. I worked really hard for the debate competition and I had not expected anything like me forgetting the debate. As I stared at the rostrum, I felt all eyes fixed on me. I grew more conscious, breathing heavily....... I heard nothing but my heartbeat. It felt like my heart would burst, I felt dizzy. I stammered a few words, I greeted the judges but after that I was blank ........totally blank. I did not know what I was supposed to say. I had always been afraid of such situations; I never wanted to end up like this. I wanted to cry but I knew that it would further add to my humiliation. The compare was kind enough and gave me some water. I thought about all that I had practiced, all that everyone had helped me with, my parents, my teachers, my friends.......everyone. Once again my thoughts drifted, with trembling hands I reached for the pocket of my blazer to check if I had the written form of my speech. NO LUCK! I had been so over confident that I had left it at home. With a shaky voice I started once again but this time too I didn’t know why I stood here. Confused, I looked up at the audience, I felt hurt. Why me? Why did this happen? I was known as the best debater in my school, I felt shattered, and I felt my cheeks burning. I knew I was blushing, tears rolled down my face. I was paralyzed. I thought about my reputation before, now everyone would know about this. I heard students whispering at the back of the auditorium, I had this mournful feeling, I wished that I would disappear or go back in time. I felt my mind whirl, I thought I'd collapse, become unconscious but .....nothing happened. I felt more desperate than ever. I wished that my mother would come out of nowhere; I'll hug her and cry out all my feelings. I wished that something magical would happen. I wished....? I had practiced day and night, I had promised everyone that I wouldn’t let them down but nothing was in my hands now. It was all destiny and luck playing with my emotions. I had no choice but to get out of this place to avoid stares, but that would make me look like a coward. I felt sick, as I staggered down the stage.... what did fate have for me now? Gossips about failure?
Great story! I would like to give some feedback. Your vocabulary is awesome and you can express yourself well but I think you slightly overdid some parts. You described everything, breathing heavily,heart bursting, hearbeat, dizziness etc etc. So much in one place could spoil the effect of your story. Anyways, keep it up!
