Hi, I can identify with your feelings of anxiety, and the self-talk, second-guessing, dear girl. What kind of place is it that you are considering for employment? Homesense? I just know they would be very lucky to have you as an employee. We "anxious" types make very conscientious employees, and from my long experience in my work, having been initially very anxious about it, that I DID learn to relax and enjoy it, and you will too! Go for it!!
Peaceful thoughts,
