Have you ever felt that you really didn't exist?

I myself have found in a small room up my grandparents attic boxes and boxes of pictures, not really sure who I am but uming the quantity of pictures I must love photography, the mirror pictures might give away that a little vanity is not strange to me, not all to odd if I really look like that, but who knows in these days photoshop can change you a lot, so does the internet, I can mirror a me who I want to be, but never will be, or can be, or dare to be. The truth is out there maybe, but who knows, but me.
