hello bismarck...
dun be so stress... u got to face the fact that life is that
stress. And juz dun worry too much, coz if u goes on like that, u
will get depression. it's very xin ku... i been thru that, crying
every whole nite can't sleep, no mood go sch, no mood do anything
and think of commit suicide before, coz i can't take the stress and
worrying about my major project coz i failed my interim report, and
duno what stupid interview, do so many reports and got so tough de
programming to do and worst still house dun have the program, so
only can worry. 
hmm.. give u some suggestions lah, it works for me.. when u r too
stress, and feel like crying or scolding anyone, juz scold out.. as
ur friend, they will understand u(my poor friend, all kena scolding
from me that time). or juz go a quiet place face sea, or face
reservoir(paiseh, my sch nearby got reservoir) u juz dun think
anything, wait till u calm down then go back to study, u will think
better.
hope it will help u bah... think more positive.. everything will be
over soon and it's not only u who went thru these stress alone.. ur
classmates also..
