I know it has been 5 years but I still want to know what happened next! If that pervert is still out there or (since your 19 now) stalking and still harassing you, remember god is on your side and he will never leave you. Pray to him (if "David" still harasses you) asking for guidance and peace and to remove your burden of sorrow. IT HELPS HE HELPS. He washes he cleanses he makes you a new.
If he is still out there, you have me and everyone on your side, don't let him control you
