Came Out to Another Friend

Today, after having a wonderful mall day with my friend Kayley and a few of her friends, I knew I couldn't wait any longer to tell her. She is one of my closest friends and I just couldn't bear the feeling that she didn't truly know me. So to bring myself some peace, and to strengthen our bond (hopefully), I sent her this letter:

Dear Kayley,
I've been meaning to tell you something for a very long time, but I have been putting it off. I have held this inside since before you even know me, not because I don't trust that you will always be there for me, but because it is a very difficult thing to discuss. I am not gay. I am a transsexual. This means that I feel that the body assigned to me at birth doesn't match my mind. Inside, I feel like a girl, just like you. This is why (if you've noticed) I flinch when you refer to me as, "your gay best friend," or imply any other masculine thing.I am in the process of changing my outside to match my inside. I have started hormone blockers so that I will not develop any more masculine features, and I am in the process of going through speech therapy to change the way I talk. Pretending to be someone I'm not has caused a lot of conflict in my life and I no longer want to feel like a depressed shell of a person. I plan to live my life as my true self after this year, and that is why I am going to home school for a year or two so I can adjust to my proper gender-role.I had to tell you this  now because I can't keep secrets from you. Of all the people in the world, I HAVE to be real and myself with you. I hope you know that I will still be me, and you will still be my best friend. I know that you love me and I feel that you will be able to come to terms with this. I will be happy to answer any questions you have and I hope that our friendship will remain as strong as ever.
Love always,
your best friend
