Hi Hayley,
A big Aussie welcome to Susan's family. It's good of you to drop in and say "Hi". Hope you like it here, and you stay for a while.
There is a mountain of information, resources and friendship waiting for you here, you just need to jump in start talking and ask any question you like. You're quite safe here and we are very accepting.
Nice name you have. I always debated the 'K' but finally went with the 'C'. Your feelings of meeting your GP are pretty normal. This whole journey is all about being absolutely horrified and overtly excited at the same time. I know of no other process that creates such a diverse set of feelings similtaneously. Hope all goes well with your GP, just relax and tell him/her just how you feel. They should then refer you to a gender therapist who will have more detail and experience to guide you.
Looking forward to hearing more of your story in time to come, but in the meantime, be safe, well and happy.
Lotsa huggs
Catherine
