Thank you Marion for the advice. The place I found is actually really close to where I live, about 5-600 meters. They specifically advertise for transgender voice therapy. So that's cool. I guess I'm pretty lucky to live in this town; I just found a cosmetic salon (also not far) that advertises make up sessions and lessons for transgender as well as a hairstylist advertising for transgender friendly atmosphere as well. So, within the town, it's pretty liberal.
Unfortunately, once you get outside and into the rural countryside, we're talking AfD land - real Nazis and dangerous.
So, for me, passing is very, very important: it's a matter of personal security. So the voice lessons are crucial. Luckily, the body I hated all my life because I'm small, my face is young and soft, and I never really looked masculine or intimidating enough to be a paratrooper and Green Beret, now is a huge benefit and I'm no longer ashamed of not being masculine looking enough, now since the beginning of the summer, I embrace it and love it. I actually love my body, yes, even the cute pouch on my belly. So I hope the hormones cooperate with that as well as the voice lessons.
We'll just have to see.
