Am I a pitiful person?

Am I a pitiful person? This question always buzz in my head today. Since i can't give a touching surprise party for my best friend. It was really disturb me because i wanted to give her an unforgettable birthday party. Hope that she will never disappointed at me.

The other things that made me feel pitiful was i break the serious situation in every class today. It was because I got a serious cough. I know that my cough is the sickness, but i still can understand why this cough get worse in every serious class that i have. :"( 

I am so sorry for made many mistakes today. I am so sorry because I have blamed my cough. Hope that tomorrow I will get better and can catch up my study that I have neglected today. Maybe this is just my negative thinking. My best friend didn't give me any complained about her birthday party and my classmates didn't blame me because the noisy sounds that i have made.
