Is what's repulsing you the actual becoming of a woman, or losing the man? I have fears and doubts similar to yours sometime, but I've thought it over every waking second I can and I know in my personal doubts I'm starting to understand. It's not so much that when I have my streaks of doubt I don't to become a woman or have desire to remind a man, but I'm afraid of change. My mind reacts by pushing away the change yet deep inside I know that I'll always be unfulfilled as a man, and I have a hunger for transition that comes naturally. When I think of myself in the fullest terms as Isadora, I feel so much more gender dysphoria than when I'm putting up the act as a man, but I also feel more true to myself. It's just society has grinded me down so much I'm really just discovering myself instead of who I morphed myself into so I could fit into society without total despair.
So, think it over some. Find the real root cause of the repulsion. But in any case, if you aren't transsexual like you thought you were but rather bigender then don't fret about not being happy because being yourself will always give you its own kind of happiness. Ultimately, just go with what in the big picture feels the most right for you, and it'll all work out 🙂
