Butterflies in the stomach

I'm feeling nervous at this very moment.
Butterflies are roaming in my stomach like I could throw up anytime.
And the reason is pretty stupid.
Guess what? I am going for my very first job interview.
Not that I have never work before, if you consider an interview to be a promoter fits the list.

This is formal!
And nope, I'm not at all excited.
Judging from the voice of the interviewer, I'm not sure if he's friendly because I thought there's a hint of mockery when I said this can be considered as my first job.
That really freaks me out.

Now, I can't help but keep asking myself why do I even apply.
It all happened in less than 30 minutes.
I sent in my resume and I got an interview, just like that.
No one seems to notice I am not prepared.

I am lost.
What do I do before a job interview?
What should I wear?
What should I bring?
What should I say?
All the sample questions and tips for a job interview drove me into a funk that is so deep I could not see the end of it.

You must be thinking that I worried too much, being melancholy.
Maybe, I'm not getting the job after all.
Another question popped into my mind.
Can I deal with the disappointment? That is not mine.

It's on Monday.
Perhaps what I need is just words of encouragement and a little faith.
