frustrated!

 a word to describe me this week.... i am so frustrated with myself & the kids~ i planned well, i prepared well all the materials, but yet they all failed! the kids are so noisy, the class is out of control... i am left utterly exhausted & frustrated.... my friend said that perhaps i had high hope, that's why i prepared things which were too hard for them... but the thing is, they were material from last year, for the same class.... *sigh* i dont know how can i survive these things for another 9 months.... i guess one way to stop feeling frustrated is to have no hope at all for them... maybe they dont deserve to be put on hope.... but one thing that really stop me from doing it is half of them do cooperate and did their work... while the other half make me feel miserable and turned the class into zoo!!!!! i dont know who to talk to, thus lead to this post.... i really pray that i will find the way out from this challenge... i guess the hurdle in teaching comes every three years.... it was terrible in 1st year, 2nd was a little bit better, 3rd was great, so it repeats again with terrible this year..... i am so tired.... i dont know how can i last this dreadful situation....
