A not so human girl (mermaid v.s vampire)

Hi I'm Sydney I was the Ordinary girl till I discover that my real parents are vampire and mermaid! I have the power of both! And I have to make lots of changes. I also have to deal with a bitch and her boyfriend. The dude I like that just attracts me. A hot vampire that likes to simi stalk you. And a sweet merboy who you think is very hot as well just nicer. Can I get through these changes? Who will I choose in boy wise. And if anything how can I just get through high school with humans!
