Help with the English....?

When I was a child my favourite singer was Ricky Martin and I loved most of his songs like "Livin la vida loca". I loved reading too and my favourite book collection was "GIULIA B." The main character was a little girl who looked like me. My favourite cartoon was Spongebob, a funny sponge that lived on the bottom of the ocean and worked in a fast food restaurant. My favourite p-time was quarrelling with everyone, this is why I had no friends. At school my clmates were scared of me because I always go better marks. My greatest victim was my cousin, she's 8 months younger than me and she hated me but unfortunately for her, she was a member of the family and we spent every single day together. I was a little devil, but growing up i became more friendly and today one of my victims is my best friend.
