I'm also 17 and a senior. I can definitely relate to your free. Something that helped me get over it is learning about the spotlight effect http://en.wikipedia.org/wiki/Spotlight_effect The reality is, most people will not notice/care if you stutter a bit, especially when meeting new people. They'll assume you forgot a word, or maybe you're just tired. Whenever I'm at a party or anywhere else where I meet new people, something else that helps is realizing that if you do stutter a lot, you never have to see these people again.
