I would have a hard time picking a date, there are so many.
Actually, I'm having a hard time with the idea of being reborn.
I can't say that I "became" Allison. I've always been me. It's just that for so long, I locked up the real me inside, where nobody could hurt me. The past 10+ years have been a gradual process of letting that me out, bit by bit, and of the real me learning how to interact with the world. Transition has for me been less a process of transforming myself than a process of changing my gender citizenship, so to speak.
Some milestones:
* August 2004 -- separated from my wife. Realized that if I hoped to have any will to live, I would have to stop worrying about what other people thought I should be and start figuring out who I am. The start of the journey.
* 2004--2013 -- saw myself as "gender non-conforming male," gradually experimented with and got used to going out wearing skirts.
* September 2013 -- read Zinnia Jones' blog post "That was dysphoria?" which led me to consider that I might be trans.
* 2014? -- My "inner oracle" (rather smugly

) told me I was going to transition. No details, though.
* Jan. 2015 -- Decided on the name Allison instead of Melanie.
* Nov. 2015 -- started HRT.
* March 2016 -- came out to my church, started finding support people (mainly people who are willing to listen to me when I'm freaking out.) It started Getting Real.
* August 2016 -- spent a week at a music and dance camp being Allison 24/7.
* Oct/Nov. 2016 -- legal name change.
* Dec. 2016 -- stopped using <deadname>
* Jan. 2017 -- started going to work as Allison.
