I felt the monster in me.....

Recently....I remembered 2 more or less years ago.....(well,I am not hear to write a granma story lah,but pls see' me out)
It was a fine day,I asked my fren Jordan(now no more frenz,for no reason,if you really wanna kno why,ask him) out to play badminton.Then a pri 5 boy came,he snatched my badminton racket(it was 7.30pm++++)....
Then he said that if I want the racket back,I hav to kicked his ball and score 3.Jordan helped me,then he scored 1,the boy said,"oh,ur fren help you,then it will be 5 scores from now,if you wanna blame,blame it on ur fren."
so,I forgot about the blaming thing,then I keep on kicking until really dark,then I started to get irritated,then suddenly,my pulse rate and rate of heartbeat changed...it turned faster,faster,faster....
And then,I faced up for no reason,then I felt like I fainted,like in a trance for a few moments.....
Like I blacked out???then,I faced back to the ball infront of me,then I started crying(cause that time I was a weakling....wait,I tot I remembered during when I blacked out I gave a loud shout until the ppl of blocks can hear it???) then the boy said,"ok lah,I give it back to you."I walked towards him and snatch my racket away,damn him.
From then on,whenever I was mad(really mad) my pulse and rate of heartbeat would go faster,faster,and the more I felt dizzy,and the more I felt like fainting away,and one more thing,my strengh,and everything would go up,and when I punch(or hit) others back,I felt no pain,and punching or hitting is much much more easy,yet harder,inflicting pain on others.
Is that the monster in me???In another day of my pri 4 years,I was in a tuition,my fren Perry played with a pen,then it hit me,then again,I went mad and attacked him.But the att of the pen made me have a bleeding nose.
However,the time when I was really mad,and the monster in me unleashed,was when the time the pri 5 boy took my racket away..............
