Disappointment!

I failed to perform well in my teknik kemahiran belajar's presentation.
I'm requested to present the part which i not quite familiar with.
I felt super nervous too! Our lecturer damn strict and act according to his mood.
During the presentation, i really dunno what i am talking with!
My mind blank!
I felt shame on myself!
I care so much for my performance!
I'm a loser, right?
Who care?!
Suck!
