This world

I will only get more demoralising in this school as time goes by. =( Such a simple thing and I could take forever to figure how to work. Its just so hard to concentrate and work on things which I don't like. The more I look at it, the more stress I am, the higher is my unhappiness level. To say the truth, I really grew so tired of this world. If only there is another dimension for me to jump in and start all over again. 


No one understand me, not even myself. =/ What is the purpose of the existence of human in this world?
