Well, admittedly, that's... not great. But honestly, the fact you find that's a problem at all shows you're learning from it. No one gets fixed overnight. That stuff takes time and everyone makes mistakes. So learn from it. Remember how reacting like that makes you feel now and try and make sure you don't do that next time.
