I have AVPD as well and have transitioned in that I'm out to everyone and had my name legally changed. I certainly understand the anxiety - transitioning was a very slow process that took about a decade for me. This was heavily because of my anxiety about what others would think. I took things one small step at a time - like starting to grow my hair out or starting electrolysis. A few people might know but not many so it's a form of exposure but so minor you won't even be concerned after some time. My initial goal was to be androgynous, full transition seemed like way too much anxiety at the time. So I think you are capable, maybe just make small changes over time.
