I can sympathsize, I was excruciatingly shy around the boys-- not that you can tell that now! LOL
Start by telling her you thought you'd be too shy to talk to her but look at this, here you are talking to her, then smile. She'll probably laugh, or at least smile and think you are making a little flattering joke. And its amazingly freeing how ratting yourself out gets it out of the way. Then ask her if she likes doing things like going to the movies or out to eat, whatever you might have in mind to do with her. This way she gets a little hint that you are going to ask her out and can mentally prepare in the next 2.8 seconds LOL (girls like to do that whether they are going to answer yes or no, okay?) Then ...ask her!
If she says no thanks, tell her thank you just the same and walk away CHIN UP. This is where every man leaves behind a little piece of his childhood so stand tall and be proud regardless of her answer, okay? You will live through this moment, I promise.
If she says yes... panic! No wait, LOL just kidding there - have a good time!
