Teenage Vamp? No Big Deal! [Won't continue this until I have the nerve to ]

Lilith, an average girl in high school who is in every angle very plain, always dreamed of becoming a vampire, with their beauty, charm, speed, strength. Lilith thought it was everything she was born for,
Then one night, when everything fell apart, she didn't expect her dream to come true, She actually became a Vampire! Would she be glad that she's finally a vampire, or be scared knowing that she could hurt her loved ones anytime?
And what if someone new she trusted hides a secret that would endanger them all?
And what if a bitter vampire goes in your way, trying to get back her (ex) mate and killing you in the process?
