Hi Jackieh,
A big Aussie welcome to Susan's family. I'm sure you'll find what you are looking for here, there is a mountain of resources and friendship waiting for you.
First and foremost, congratulations in coming to terms and acknowledging your feelings. That first step is always the most daunting. The next thing you may wish to consider is finding a therapist/counselor who understands TG issues, who can guide you through the labyrinth of emotions and feelings. They should be able to point you in the direction of the options available to you.
And don't worry about your age. If you decide to transition, you just get younger as time goes on. It's true, someone mentioned to me last week that I couldn't be over 37. I've since referred them to a mental institution

Look forward to hear more about you in time to come, in the meantime, be safe, well and happy.
Lotsa huggs
Catherine
