Thanks, Sephirah! That's exactly it. But it turns out that I didn't need it. I'm his first transgender patient, which I admit is really scary. But he's kinda being mentored for me by someone who's had a few, and he studied near the Pride Center in Minneapolis and has had a lot of LGB experience. He's really nice, and doesn't really seem like he just wants to agree with me. He actually is taking a scientific approach towards diagnosis, which really scares me. I have no doubt that if he feels I am actually trans he'll write me the letter, but he was telling my parents about people who actually convince themselves they're gay/trans. But, insurance pays for all of it. So I can't complain too much. With school coming to a close, I'm going to be indulging in my feminine self with actually getting my eyebrows done, probably frequently wearing makeup, growing my hair out again, maybe even getting my ears pierced! I'll do everything I have to in order to convince him to write me the letter. I'm also coming out to my older brother whenever he gets off work. My dad told him that I was going for depressional issues(which I guess is partially true), but I wanna wear shorts this summer without having to explain why I shave my legs.
