Hello Jane. Welcome to this group; we are glad you are here. As you have probably discovered it is important as trans girls to write down our trans story. As you go through your journey you will be asked many times about it, especially when you come out to others. Initially it will be very scary to open yourself up to others and then one day it will just roll off your tongue as if you were talking about the weather.
Also, this journey is not something we can do on our own; it takes help from other trans girls. It is always best if you can become friends with another trans girl that is farther along in their journey. Not only to talk about the many transition issues that try to throw up roadblocks but someone that will talk to you in the middle of the night when things seem too hard to continue with the process. We have all needed that good friend who loves us for who we are and will never pass judgment on us.
Have a good day and again welcome.
