"With the exception of certain names like Elizabeth, I find that most people will generally call you by what you introduce yourself as."
I disagree, I always introduced myself with my calling name, but it always seems to be nicknamed (either by using just the first three syllables or dropping the last two)
Both my mother and I hated this. The first wasn't even a proper nickname (like making Cri out of Cristiana) and the second was a boys name.
It's one of the reasons I don't use the name anymore.
