I'm so nervous!

I have to admit something. I am so nervous that I have made myself sick. My heart is starting to race and my stomach is squeemish. I feel like I could upchuck.

Why? I have a job interview tomorrow at 10 am. And I am so ready to call them and say "Never mind! I really didn't mean to turn in the application." But I can't - I told my co-workers and my supervisor that I was applying.

Sheesh. What have I gotten myself in to? I have a great job and a great boss. I have a ton of vacation and sick days. I have a boss who tells me to keep track of my time when I tell him I need to take Ster to tutoring or to a doctor's appointment. I like my co-workers. Well, most of them anyway. I know my job - I know a lot about my city. I know where to send people when they have questions I can't answer. I can drop Ster off at school on my way to work and get him to day care easily. I work 8 to 5 and like it (other job works 4-10's and I am pretty sure I couldn't get to work by 7).

Not that I'm assuming I have the job. Because I'm sure there are a lot of qualified individuals who have submitted their applications. I'm assuming I won't get it - but what if?
