Hello there, Jaeger. I'm obviously a newbie myself, but by no means new to those sort of feelings. I've often worried about what happens when sometime in the future, I make that final transition- not everyone is quite as accepting as this community.
Now maybe I'm wrong, but the best thing I can tell you is not to let those aspects of your past self you've left behind define you in the present, but also not to give up your past. Transitioning from your "birth sex" is not something to regard as a simple wave of a wand; there are so many levels to what makes up a person, and while gender identity and expression are but a part of ones self, they affect nearly every aspect of day to day life. I understand your rejection of all things female- in fact, my room now looks like it is being shared by a male and a female who have a complete clash when it comes to personal tastes. I've lost some of who I was along the way, and certainly have a long way to go on this journey, but the person I truly am has been kept intact. I have gone through and am currently going through a very long process of transformation, which you most likely will as well. However, that never has to mean losing who you really are along the way.
That being said, welcome to the forum! I'd love to hear more of your story, and would certainly be an open set of ears should you need someone to listen.
