Spondiferous,

Please know that whatever you're feeling and how ever you might identify, that that's real and completely valid. There are no wrong genders and there is no wrong way to transition. I think your plan of just starting somewhere small that's manageable is a great place to begin expressing yourself.

And if that works, and you want to do more, great... And if it doesn't, great... And if right now you feel more closely identified with non-binary and in a week it is more masculine identified... That's great.

Identity is completely fluid. And no assertion of that identity is ever fake, or unworthy. Don't worry about all the steps, and the whole plan of when should I do HRT, when should I go for surgery, when should I....

The answer is, in my experience, you will when you're ready.
Just start small... Start taking a small step out from being right in front of that exhausting wave of constantly pretending to be someone and see how it feels, and when it feels right... You'll take another. And whatever path is made by all of those steps, it is the one that's perfect for you.

Lots of love.
