A Huge Mistake

Hi, guys. As I told you the other day that I was going to perform for English week and... yeah, I freaking messed up. I screwed up big time. I knew I had it all in my mind but something happened with made me forget that particular part instantly but in the end I still continued. Without full satisfaction, I just couldn't move on. It was like this scene that doesn't come out of your head and just stands there haunting you every minute. Every time I try to forget about it... I couldn't. I just... I can't. I hope this mistake doesn't affect anything especially my studies. I can see that today wasn't my lucky day but there are second chances... I hope.
