Chemistry Paper..

Today's my first paper, Chemistry. Studied till late in the night yesterday and woke up early to study today as well. But when i saw the paper, i put too much stress on myself and became so nervous that i forgot everything. Whatever i studied didn't come out much. I walked home cry and i continue even when i was showering and went i took a walk after that. Whether i do well, it's also depending on this paper. I can't possibly score full marks for Physics. And.. I already feel like giving up because i've flung this paper and it doesn't seem to matter even if i study so hard for the rest. What difference will it make? I wondered to myself whether i was born a failure. All my life, no matter how hard i work, i still fail. That's why i've given up long ago until i decided to work hard again. And this have to happen. I'm not asking much. I just want to get through secondary school and get into a poly. And why can't i do that?!! I hate myself for not having a brain. And now the tall buildings are temptations to me. I really don't know what to do with myself. What do i have to do just so to do well? I've studied the shit out of me. And still i can't do well. Ahhhh!!!!!!!!!
