Hey Jayne,
It might be good to take your mind off your gender a while. That's hard for people in our situation (we've just discovered that we're trans, we don't really know "how trans" yet and we don't even know how to find out.) Your gender is currently a source of anxiety and "spiraling" mental processes. It can help to take a step back and really get your mind off your gender for a while. The less you think about your gender, the less it will bother you. Certain things will come naturally, and you'll think "oh no, boys can't... oh wait... I don't need to listen to that voice anymore." Other things won't happen -- you might not actually want to voice training, or srs, or whatever.
Of course, when I suggest that you not think about your gender... I'm speaking from the experience of thinking about nothing but my gender for months on end and having an absolutely miserable time of it. Aspects of my life forced me to think about other things (I did not up and decide to not think about my gender) and things got better for me. Actively deciding "I'm not gonna dwell on X" has a miserable success rate in my experience -- but that's something a therapist can help with.
