Oh lordy! Congrads to you! On my wedding day, I was too stressed out to be nervous. Even though we went to Vegas to get married, I still stressed, all in all, I had nothing to worry about.
Just let all of the little things go, don't stress over anything, enjoy yourself. All the people at your wedding are there because they love you and your new husband, they want to support you guys, and see you enter into your new lives together.
GOOD LUCK! I can't wait to see pics!
