When i started therapy I was pressed to take a new name and in a hasty choice, I picked Noah / Noa, which despite the male significance, everybody reads it as "Noa", and with the 2 years letters I could update it to Noa later.
Sadly, right now it seems too male for me. I picked something neutral at a stage where I was pretty unsure about how far into transition I wanted to reach. Feeling fully female now, I am not interested in that one, although I now have documents, business card... You only get to change it once, and now I am quite unsure.
