Actually I did this today too. Only, my hair was a mess and I am overweight, but I was just OKAY with it. I think maybe it was because I was exercising when I happened to see my reflection. I didn't have negative emotions.

Remember: Sure, I need to fix some of my behaviors, but I'm not a person with less worth because of them. Behaviors are external to the person, you can dislike your behaviors, but don't let it reflect on how much worth you give yourself.
