It's just occured to me how unusual it is for someone to be unsure of their own name, or to be considered two different people, for that matter.
My parents forenames are Rosina and Lindsay so I was christened with the name Roselyn, which somehow morphed to Roselynne over the years. But no one ever seemed to be able to pronounce or spell my name correctly, so I changed it to rozallin, because people call me Roz anyway and there are only two ways of saying it as opposed to many.
I'm planning on changing my name to my name by deedpoll when I turn 18 because some of my official documents are under R. Thompson, and some are under my father's surname (because my parents weren't married at the time I was born, so I took my mother's ex-husband's surname, and then unofficially changed my name to my father's surname when I went to school to stop me from being teased).
Rozallin J. Thompson (I think)
