What the Hell Happened to My Face?

Do you ever leave the house and think "Yeah, I look alright today." Then you get where you're going and catch your reflection in something and go "What the fuck?! How did I let myself go out in public looking like this?" This seems to be a constant problem for me. I don't know if the lighting in my house is very good or very bad, but I never look the same here as I do anywhere else. The lighting at school seems to be especially cruel though. I go into the bathroom and actually cringe when I look in the mirror.
