im terrified to transition

im 26 and don't think passing as a cisgender woman is in the cards for me, as im 6 feet tall and hve a very deep voice. I don't mind this fact too much, from a body dysphoria point of view. But I do from a social one. I'm aware I will be treated poorly by many people. I accept that I need estrogen and want to dress more feminine, but maybe I can present as a femenine man? idk. im tired. Im excited because I start e next week but im more scared than excited. I already feel isolated.
