screw up

I screwed up my muet paper.

I totally screwed up.

My mind was a complete blank when i stared at the complicated text. Everything was blurry. I fail to understand anything. Had a hard time answering.

And my mind was flying to slumber land when i was doing the listening test.

I felt terrible. I felt like a total ass.

my brain was filled with disturbing thoughts of exams, assignments, my future and "what-the-hell-am-i-doing-here-in-the-1st-place" questions.

I was lost of words. totally lost and blank.

I seriously screw up this time. I just can't take it any more.
