My support to you! Just remember that the best of us mess up on work sometimes. It is part of the situation at a workplace. EVERYBODY from time to time makes some mistake(s). It is embarassing and might make your co-workers unhappy for a little while. But pretty soon it is someone elses turn to mess up! People forget what happened, workers have far too much on their plate to keep track of every mistake someone does. Sounds to me like you have a strong ethic about working, and that is a thing an employer notices. Just try to put it behind you, and pretty soon other things will be more important that this.
