Hey! I had this problem last week, sort of. I came out to all my teachers last year, so this year when going to the counselor she already had a gist of who I actually was. Now, as a suggestion, I just say try to stay calm. I know personally when nervous I get kinda shaky, so staying calm is a big thing. Just be casual, once you sit down, just tell her you'd like to have your teachers call you by your preferred name, and use male pronouns, after that I think she'd just get the hint. And as Liam said, make sure you email your teachers, and also tell your friends to call you that, change your Facebook/Myspace/Friendster, whatever social network you use, to your preferred name and what not, after that, everybody will get the hint, and then you've got the whole school going by your preferred name and male pronouns. This is all just from my personal experience at a school stuck between a cornfield and a cow farm though so I don't know if this will all work for you, but I sure hope that everything goes well for you!
