This is a really interesting topic. And I think I've gleaned something from all of your answers, particularly Donna E, Ryan55, Hikari at the moment. It's good to read all of your answers and I can hugely relate to some of your feelings.
I think if I were born female, or vice versa in the case of FTMs (someone's said already), just how much could've been bypassed? i.e. no worries about having to take hormones, no guilt, no need for any money for this purpose, we would just be that gender and that would be that. In that way I feel a little indignant at nature. But obviously we just have to make the most of our circumstances.
I do feel proud in that I'm finally getting to grips with this issue finally, and being able to relate to so many of you, but I also do feel afraid at times particularly what others might think (not that this should deter one from transitioning), my father is in the know but I still haven't told my mother yet (not sure when to do this yet, I see her very rarely). I don't think she will surprised, and I'm pretty sure she will be supportive, but there's still that nagging doubt.
So, I ticked: Depressed, Proud, Scared, Excited, Comfortable...(at various times). Right now I'd say I'm comfortable.
