Happy Birthday, Shelly! I hope you're having a great day.
Don't stress over the thirty thing. I stressed my entire 29th year, and then when the big day arrived, I was actually rather happy to leave my twenties behind. I felt more like a "woman" than a "girl", so it was fine!
I'm with Sundancer -- you're a kid!!
Take it easy, and enjoy your special day.
