I went full time about 6 weeks before hrt.
Do you know that mtf HRT has no effect on our voice?
I didn't pass then, and still don't pass now the majority of the time. However, the HRT has softened my skin and slowed hair regrowth, Ive done 2 rounds of laser hair removal on my face, my anxiety is better, and Ive become more comfortable in my skin (and have improved at finding a style that I like and fits my shape). So i'm on my way!
I think that the best thing about waiting to begin HRT before presenting full-time is that it really helped with anxiety once I did start.
I don't regret it, because I didn't have a choice anymore. It felt desperate, like I couldn't go another day living as a man. I did it for myself, not other people. It was very challenging. People always staring at me as I went by them on the streets or in grocery stores. It exhausted me mentally because I was often in a fight/flight/freeze state.
Positivity is exceedingly important, despite if you pass or not. If I had to start over again, I would employ the constant, positive self talk that is so transformative to my experience. I tell myself I am beautiful and lovely everyday, despite if I am looking like a boy or not. Its incredible how our bodies and spirit respond to positive, self talk. It can completely alter my experience.
