I hopefully get to start this coming march. You gotta be strong, and don't doubt it. Yes it's a big step in your life, and change can be scary and exciting. But if you surround yourself with people that support and love you, everything will be okay. I have a group that I talk to online filled with a huge group of different people. All that can't wait for me to start transitioning. I've already been asked to be a brides maid. But most importantly you got to have faith in yourself. This is something you are doing for yourself, no one else. And it's something you deserve. And don't let anyone tell you otherwise, even yourself.
