Don't know why!

haiz... look at the clock...it's almost 1.30am... actually it's still very early..haha... BUT... i don't have the mood of sleeping at ALL... Today i wake up quite early,moreover,the other night quite late then only slept. I'm having activities almost the whole day... until dinner time then only back home... i suppose to be very very tired and can sleep within the count of 3...actually i realy realy felt that soO... After dinner, i'm still as usual... the normal me!! XD However, i plan to sleep after briefly checking mails...it's around 11pm++.. BUT... i also don't know why, i can't turn off the computer, just click here and there with empty soul.. Then...slowly...the quite night CAME!!! [All people around me slept and stop making any noise,except for the sound of my fan] " it's the time for you to sleep now, Sze Wei!"...i told myself!!.. BUT... i don't know why,i just can't let my body to rest... to enjoy the feeling of sleeping... to enjoy my lovely pillow... to enjoy the breeze of my grey's fan... i just don't know why there's a sudden pressure in my mind to let me just be awake and not to sleep... although i'm really tired because i spend lots of energy today... i don't know!! it's just like the mixture of problems in my mind... i can't seperate it out... i already tried to think it carefully,but i can't think of what's actually the problems in my mind that interrupting me... I DON'T KNOW!! P/S: i can't write more because the internet is keeping can't connect!! I also DON'T KNOW WHY!!
