Science is not based on "feelings". You are not biologically the opposite gender of what you were born as because you "feel" that you were in the wrong body.
You need to accept the fact that you were born in the right body. You just feel wrong.
A man cannot know what a woman "feels" like because he was never born a woman, he never matured into a woman, nor was he socialized as a woman.
A woman doesn't know what it "feels" like to be a woman either. Because woman isn't a feeling a feeling, it's a sex class.
