@F_P_M: it's the waiting. I almost had no milestones at all to report in 2018, just waiting. Only one psychiatrist appointment, that I had to wait a year for, brightened up the year.
There is so much waiting in this process. Waiting to get appointment dates, waiting for the dates to come around, waiting for professionals to write letters, waiting for legislative changes to happen, waiting for them to be implemented, waiting, waiting, waiting. I'd have finished my transition in less than a year if I'd had my druthers. And I'm not getting any younger.
