I haven't been out (this time) for two years yet. I think I came out in late summer of last year. I lived as male for awhile when I was younger, but then I got an on-the-books job and chickened out on transition.
So I'll go with one year. After one year, I've filed for name change but it doesn't turn final until Feb 3rd, most people get my pronouns right, I have my DMV gender letter but obviously can't use it yet, my kid calls me daddy (I let her decide on her own when to switch to that), and I've been on T for about a month. On the surface I'm a complete loser (no career, living in a sketchy studio, bad credit, disjointed history, etc), but I'm happy. I'm finally at ease because I'm finally being myself. It's pretty sweet.
