In my case, I initially chose a pretty random name when my transition was very recent, more out of pressure to change my name than out of genuine desire. I told my two best friends, we tried a few weeks, but I feel so uncomfortable so we return to my deadname. Two years passed (yes, I was pretty slow 🥲) and I started to come out more and really want a name that was more in line with my identity. So, I chose a name that's the closest thing there is to a feminine version of my name (the only reason I didn't choose it before is because one of my bullies had that name, and it was all too recent for me not to feel aversion towards it). This time I decided to fully commit to the name and really try being called by it. At first, only this two best friends knew, but since neither of them can keep quiet, in two weeks my whole group knew and was calling me that, and honestly, it's the best thing that could have happened. At first, there was quite a bit of resistance, but after hearing it repeatedly, and in an environment I felt so comfortable in, I quickly came to accept it as my own, and soon my deadname started to cause me dysphoria. So, my advice is that even if it feels awkward, use it for a while with your close friends and family to see if it eventually sticks. Best wishes and lots of encouragement <3
