Nervous

Guys, i feel so NERVOUS right now!
I don't know why do i feel so scared suddenly.
I have a job interview later at 430PM at Wisma Damai Point.
I don't know what else should i prepare and i don't what to wear later. Well obviously I know i have to wear formal attire but i just can't make up my mind which attire should i wear later.
I prepare everything like all my academic result and other qualifications but i'm not so sure if i left out something.hmm.
I hope my interview goes well cause i kinda need a job right now for temporary and to gain new experience in different company.
I really hate this feeling and i hate when my heart pumps very fast..:(
but one good news, a friend of mine is working there also so if i do get the job there, i wont be so sad and "forever alone"? :D
Oh well, wish me luck? :D
