the interruptions, credit stealing, and mansplaining were no longer incogruous with my understanding of my gender. Which was ... retroactively confirming in an infuriating kind of way.
I also had way more confidence afterwards because I was no longer pretending to myself nor anyone else to be a boy or a man. It turns out that that's a huge mindfuck and takes a massive amount of energy to maintain.
Once I was free of all of that, I was able to engage with a genuineness and curiosity that people around me noticed and reacted positively to. I went from being someone who probably had more potential than they were showing, to a well-liked leader and innovator.
I still had to deal with sexist (formerly understood as bullying) bullshit, but once I trained those people in on how not to talk to me, many of them became my strongest allies.
