Hi, Megan,
Get thee to a therapist.  Or, at least to a TG support group.  Better yet, if you can find a place where trans people congregate, umm, hang out, go there and sit and talk.  You'll likely discover a whole lot about yourself. 
What you feel is similar to what I went through, but in my case it was during my tentative first steps of coming out into the world.  Yikes...the life of a tweener.....
