Slowly, very slowly. Lots of research, lots of time for family to get used to the ides, lots of planning about what to do about work, meeting other trans people, building up a support network, understanding the risks. Learning about and understanding the standards of care.
Now the ball is rolling, initial consultations complete, referrals under way, dates are being set, and the transition process has started.
Some people jump in and get it all over and done with, I prefer one small step at a time, at my own pace. I have already started working as Ruth but it will be October before I do my legal change of name. Living two lives can be complicated but it can be done and it gives time for those around me to adjust to my changes.
Good luck with your transition, I hope it works out well for you.
Ruth
