why can't i get a job?

i moved to charlotte to get in the banking industry. i tried so many company's in my old hometown so i moved. i have had interviews with three banks and two have turned me down, the other is pending. one was because i forgot to include a job that i had for only a week on my work experience. they said i couldn't apply for 9 months. the morgage bussiness would be another industry i would like to pursue but i don't have a degree. i have been waiting tables so my experience is limited. i feel so insecure now like i'm destined to be a failure.
