I did it, I finally was able to start the process of changing my name and gender legally. Now it takes just 3 more months until the change becommes official. It feels so fucking awesome knowing that I just need 3 more months to be able to change my name and gender everywhere and not having to use my deadname anywhere at all. It fills me with so much euphoria.
Best wishes and congrats!
Beware the random marketing emails in the future, they have a tendancy to deadname due to out-of-date information. On the other hand, easy to filter out because of that.
