What do you think to the start of my story?

I'm 16 and i do this in my spare time. I've written this this afternoon.

The wind blew my long hair behind me. I wondered if flying felt the same way; if it felt so exhilarating. Riding my motorbike at illegal speeds on dangerous roads, knowing I was in no danger, was my escape.
I hadn’t always been this way. I hadn’t always been so reckless. I was once an ordinary teenager with the usual cliché problems girl’s face during adolescence. I wasn't that stupid teenager anymore. I had a new life, filled with secrets and mystery. I didn’t choose it, it was chosen for me.
I knew there was no way to ever go back to my family. I would miss them all immensely, my brothers Mike and Austin, their constant teasing and tormenting, my lovely supportive sister’s Amelia and Rachel, but most of all my kind and caring parents Jack and Grace, oh, I was going to miss my mother, but I couldn’t let myself think about them anymore, it hurt too much. I had to learn to forget them; I was going to live for forever after all, forever seventeen. I couldn’t live the rest of my existence grieving my family; they didn’t know what had happened to me, I had just disappeared in the middle of night, how long had it been now? One year, maybe? Had it really been that long?
I knew I was unrecognizable by now; I had gone from the plain girl Melody, to the ravishing enchanting Melody, who was no longer even human. My skin used to be a soft ivory colour I had always been pale, but now I was paler than porcelain dolls, my skin was cold like I’d been dead for hours. My hair was silkier and shinier than it had been when I was human; when I was human it had been a dull black. My eyes however had changed the most, they had once been a dark blue but now…now they switched between red and black, I wore colored contacts to hide them from people, but I can still see the tint beneath. As a child I always loved playing in the sunshine, it made me feel warm, full of energy and happy, now it made me feel weak, sick; I tried to avoid going out in the sun as much as possible but sometimes it is unavoidable and I have had to suffer afterwards.
Nevertheless there were benefits to this new life I had been forced to live, my new incredible inhuman speed and strength certainly, and not to mention the unimaginable beauty; even though I no longer looked like myself. My favorite is the invincibility, that I can do the most reckless things – like riding a motorbike going over a hundred miles an hour on country roads – and not be putting myself in any danger. These I could live with, but the one most unbearable thing that I wasn’t so sure I could live woth would be my new diet and the thirst when I refuse to satisfy it.
