The result of yesterday affected me as it was because I was able to go to bed by 3:30 in the morning. It was so terrible. Until then, I was thinking of the topic again and again but I had no clue. It was the most tough, difficult topic I had ever had before. I was running out of energy. Nonetheless, I should get it finished somehow (or other) and I did it although it didn't satisfy me. I thought it was making a fool of me at that time.
