Talk:Deadname

So, I want to change my name, but idk if I should. My name is a traditionally girls name, but, the only name that i've considered changing it to is David. The problem with that is that there is a David in my grade and, my last name is David. Should I stick with S David, or David David. Should I just ask people to call me by my last name? I'm not gonna say my real first name.
