Being shy is a really common problem especially amongst teenagers. But the good news is you can almost always overcome it, or at least learn to deal with it. One of the best ways to deal with shyness is to "rehearse" situations that make you really shy. Once you've done it a few times, you'll wonder why you were so shy.
Don't give yourself a hard time if you make some sort of mistake — you are just human! Forgive yourself and correct your mistake.
