out of my control

i think...i didn't talk more than 10 sentences in school tdy...in class, i was sitting alone, trying to pay attention on what vasantha teach...but, i dunno...i just can't concentrate...i feel sad, moody, all at a sudden...and i realised i was actually, sobbing...i couldn't control... a few tears escaped...and i can't tell why...i think i'm just evading...
