I can't think of any solution to your situation Daybreaker apart from try to make amends to her parents to keep the peace. (Ones that would probably involve getting them something, listening to their diatribes and your confession of guilt followed by swearing never to repeat what happened again). I understand that would probably be very difficult, but since it's probably the best way out I think it's worth a try.
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
