I went full time -way- too early, I got extremely lucky but there was some major hurdles I had to go through. I know it's hard, we all have done what you are doing, some of us have completed our journey, others are still on it, but we all know and at least understand this much!
If I could go back and do anything different about my transition, it would be going full time so very abruptly, I would have slowed my transition down by about 6 months, slowly changed my dress and applied make-up to make a more gradual change for people and to let them get use to the idea over time and not suddenly go from the alpha male to a very confused and lost 26 year old going through reverse puberty while trying to rediscover herself!!
I know the desire to be you to the world, but a lesson that took me around 3 years in to learn, it really doesn't matter how the world sees you or perceives you, it matters how you see you. If you really feel ready for it, then the best of luck to you and just remember to breath! But if you can slow down going full time and make a slow transition time of 4-6 months where you slowly apply make-up and alter your clothes, then start getting friends and co-workers you're closer to using the correct name and markers before expecting everyone to do it will make your life much easier and make it easier for them to get on board as well.
Either way, listen to the girl inside you, start to let her out and let her introduce herself to you. She's an incredible person, and she's dying to show you how amazing life is and how absolutely beautiful colors are and how intense smells are. Prepare to chase the rabbit down his hole and just remember, it's ok to eat the cake, drink the kool-aid and go through the door!!!!
