How did I become this way?

My Back story

My life as an only Child wasn't what you'll
imagine. My father and mother divorced but lived in the same house. Still pretending to act as if they're in love. It made me sick. You see,my father, loved his organization for villains/Immortals and in fact he is the head of it. Which he makes millions or billions. My mother knew and was a 2 faced woman. See she had this power where her eyes changed do to emotion or something. But she also was Suicidal to her self. On my birthday, she told me something but I can't remember what it was. I was only 3 and the next day she disconnected herself from this world . Knowing her death I wasn't sad for some reason and my father laughed. My father decided to make me feel life less and training me as the head of his organization. Knowing and feeling pain by getting beaten up by your own father to make you stronger really makes an bloody mistake. Because my dad made me half Immortal . Begin trained, study different languages, learning how to shoot and kill, and begin beaten by my father was daily routine for me. See if I made one mistake and his minions or maids told him. Dad will take me to a room and beaten me . Last year this insane doctor gives me shot to awake my Immortal self and today is My birthday which made my Immortal self awaken.
My human name was Ab, my vampire name Heavenly ... and am his daughter... starting this year I'll be 16 forever.
