Self confident problem? YUPP. :(

I really have no confident at all.. what should I do? I don't know either. Today only I realized that I don't have any confident. When BM time teacher make us read the poem with melody and I was like "SHIT! Malu-nya" I tried to use Marry U but when I srep out of my place my hand just become so cold because I'm scared. DUHH. As if I'm not scared that won't be Ng Zi Shan. LOL! still teacher want me to try once again on Thursday. :((( Gosh! I don't wanna go school already.
