Tammy, one of the first things you have to learn and accept about all of this is that you have to take control over your own life and take what you want from it, nobody is going to simply give you the right or the permission, you must impower yourself to do what you feel is best for you in the long run, no matter the dangers, pitfalls and uncertainties of the shorter term.
To successfully transition, you must first of all Believe in yourself without question and secondly, trust in your conviction, and 3rd, follow through with the steps necessary to accomplish it. If you question yourself about the necessity of this, then it may be best to back off, and if the sacrafices you will have to make are to much to pay in your mind, then again, it may be best to back off. Go through with it or not, once you come out you will have forever changed the course of you life, so you must be totally sure of what you are doing. This should all be worked out with the help of a good therapyst, who will help you focus on your life priorities and the gains and risks of those priorities.
