Anxiety When Applying For a Job

Let me preface my question by saying that in most areas in life, on day-to-day basis, I don't feel pressure of 'social judgment'. I kind of just do what i do.

I'm looking for my first job in IT/programming. How do I stop worrying about what the person reading my cv/cover letter will think of me ? Yesterday I sent my first application and couldn't sleep all night. I woke up several times during the night with panic and sweat. And now, i'm mortifed to send another one.

Is this sort of feeling normal ?
