I cant even make my mum proud of me, everyone is comparing me with other plp... hmmm... I HATE IT.... It is really meaningless for me to stay in this world.. I know u will sure scold me for saying this but this is true..... I did my best but wat i get back in return....

I will try my very best and put more afford in everything i wan to do.. See how it goes... This is wat i can do for this moment..... STOP CRYING, STAND UP & WALK...
