I can really relate to this. I've tried so, so hard to stick with the "female" identity I got handed, out of guilt over the damage I was going to do if I even began to step away from it. I basically had to reach breaking point, where I just couldn't contemplate going on anymore, before I took the simple step of even saying to myself "I'm not a woman, I'm a third." I felt guilt over the thought of making the people in my life deal with it, guilt over making "normal" society deal with it. And on top of that, I felt tremendous guilt for leaving it so long--for embracing and benefiting from gender normativity while other people were standing up and addressing the issue, putting their bodies on the line. I felt--still feel--like I don't deserve to identify as third because I didn't start early enough.
