stress moment

Haiz... currently i faced many problems in my study. Last Tuesday, when i arrived at my campus, i met my lecture. he told to me that i have been chosen as representative for a writing contest in Padang. He said that minimum i will get the second runner in that contest.
For other people of course will be very happy to hear that. But for me, it is a burden. WHy do i say as a burden??? because now i am in 6th semester have many projects and assignment to do. So i more focus on them rather than this contest.
I am really confuse, should i do the best in that contest or not? because if i win as the winner, i will go to Aceh or Banten to continue the contest in the higher state.
Mean i will leave my task and school assignment. I am worried that i will failed in this semester. This semester, i need to do the research for complete my thesis.It need long time to done it. But now, i need to focus on other things. So, i am really really stress and dont know how to do.
My friends told me that this chance is a very nice chance for me to make my life become meaningfull. I am also agree it.
Haiz... this monday, i will fly to Padang to attend the contest, i really hope that it can be finish soon and i wont take part for further again.
