Welcome to the family, Jayd. Thirty is a great age to transition. Just take it as slowly as is comfortable for you and anyone really close to you. IMHO a good Gender Counselor is a wonderful help as is at least one fairly close friend, LGBT or not, who is willing to learn and support you.
Some days may be hard, but the rewards are great: You get to be true to yourself. How cool is that?
Forums can offer lots of help, but do consider coming into CHAT, too, where you can 'talk' real time with others in transition.
Best wishes.
