I think it changed how my mind works, yeah. Or at least transition, on the whole, did. There is a confluence of change going on there all at once and it's hard to parse the cause of any one thing.
But I do believe my mind has changed, mainly just cuz when I read old things I have written I don't recognize that person, and the thought processes going on in the writing seem so foreign. It actually makes me feel very uncomfortable cognitive dissonance to do that so I avoid it at all costs.
I had a lot of interests change, some stayed the same. It's all a part of my evolution, which every person, cis or trans, evolves over time. I embrace the things that stayed the same cuz those things that survived the gauntlet must be genuinely me. Why did I transition other than to be genuinely me?
The new things? Well there may be lots of reasons why I might find new interests given how much my life has changed. No clue if hrt played any role. I find female led music resonates more with me than before, but I am fairly certain that is due to life change and not because of hrt. I get female struggle now, so much more than before I lived it. I also get female triumph and how that feels. Um...I always loved shopping, so that isn't a new thing. Idk...
I wouldn't hope for certain changes. i would just try to become the best version of yourself you can be. For trans people, transition is usually going to be a part of getting there. Once you have transitioned you find out just what kind of woman you are. Some women have a masculine bent, and it doesn't make them men.
