Glenn,
I understand what you are talking about, thought I am on the other side of the desk. You see, I am a transsexual high school science teacher.
I know you are already aware of this, I cannot overstate one little thing. Once you are out, you are OUT. There is no going back – at least not at your present school. Be absolutely sure you want to do this. If you have ANY doubts, you can wait a year or more to make sure you are ready.
With that said, let me share my thoughts.
First off, you have a LOT to do and little time to do it in. Your parents/guardians will need to be involved.
You and your parents will need to meet with your principal and bring him/her up to speed. You might be surprised at the amount of work that has to be done to prepare the faculty & staff for your transition. I know I certainly was. Your parents/guardians will need to be there because they will have to approve of your transition. It's part of the gig. If they are not onboard, your transition won't happen - or at least not successfully.
You MAY be asked to delay a year so that the faculty and staff can receive diversity training on transgender issues. Are you willing to do that? Only YOU can answer this question. I did delay everything for a year, due to other issues, and I think it helped me a great deal. This is your call.
While I am NOT a fan of HRC, they do have a lot of information that you can download for free regarding coming out. Bring it as well as lots of copies.
Go to the National Center for Transgender Equality and download info there as well. Bring them up to speed about your transition.
If you have a local LGBT support group, contact them. I have the Gay Alliance of the Genesee Valley. See if you can find something similar. Don't let them be caught unawares. I was publicly out'ed before I could contact them, and it makes a difference as to how they respond to the media.
Speaking of the media, be prepared for the news vultures to circle around you. Like it or not, you will probably be the lead story for the evening news. Use caller ID to screen your calls and don't talk with the press. The less people talk with them, the faster the story goes away. The faster the story goes away, the faster you can live your life. I know this from personal experience so trust me on this!
Contact GLAAD and bring them up to speed as well. The Gay Lesbian Alliance Against Defamation will have important information for dealing with the press.
Your first few days of classes will be tough. Partly because you might be avoiding the press. Partly because you are the "new kid." Partly because you are getting comfortable publicly being in your skin. This feeling will pass quickly.
People will make mistakes in how they address you. It is human nature. They knew you as (blank) LONG before they knew you as Glenn. Don't take slip-ups personally. Keep a smile on your face and move on. If you are repeatedly called by the wrong name, or if it is obviously a slam, report it at once. Don't tough it out because that will encourage more verbal abuse.
Set up a weekly meeting with a counselor at your school to talk about how things are going. You may want to meet with the counselor daily for the first couple weeks. After that, you will be old news and you can probably go to a weekly meeting.
Report any physical or sexual abuse IMMEDIATELY!
If you have a Gay-Straight Alliance in your school, join it! If you don't have one, think about starting one NEXT YEAR. You have enough on your plate as it is!
Don't be surprised if a number of your peers start coming out to you. Like it or not, your courage will be a role model for many who are still deeply closeted. As such, it is important that you stay on the straight & narrow in regards to your studies, behavior in school and around town.
I know that this is a lot, especially for a sophomore. It was a lot for me to do, and I was 50 (ancient!) when I transitioned at school. But, you CAN do it!
What you will find is that you stand straighter. Your self confidence will skyrocket. You will find that you have a backbone you never knew was missing. Why? Because your body and soul will finally be in harmony with each other. In all my journeys, I have found nothing that can compare with being at peace with yourself.
Remember. You do not stand alone. Every one of us here stands with you.
Qa'pla!
