Ethan, there are no hard and fast rules for how a person is supposed to feel, or be, in order to transition. A lot of the time in the media, stuff is sensationalised to a degree, and extremes are reported to get people reading/watching. That absolutely does not mean that how you feel isn't valid, or worth exploring. It doesn't mean there aren't people who feel the same way you do. They may just fly under the radar.
Doubt is natural. It's something you see time and time again from people contemplating the first steps in their journey. You have a little voice inside telling you one thing, but a lot of voices outside telling you something else. Sometimes, if you don't feel confident in yourself, it's hard to know which to believe, or which to follow.
Like Moni said, see if you can find a therapist who has experience with gender issues and talk to them. Tell them how you're feeling. Take it from there, okay? How you feel and what you want matters, Ethan. It does. This is your life, hon. The fact of the matter is that you're thinking about this, and it's a part of your life. So it's something which needs exploring.
