When I would mess up at work, it would make me feel so terrible about myself. Sometimes I would get defensive about it, and other times I would just sink into a pit of self hatred and despair. You sound like you are accepting responsibility, not defensive and are using this as a growing experience. All very mature! I respect and admire your ability to see your error and take precautions not to repeat it. I'm sorry you feel so bad.... Be sure not to beat yourself up and keep things in perspective (which it sounds like you are doing). (((Hugs)))
