Jamie, first and foremost, you need professional help...
It would appear dear old a-hole dad is pissed you withdrew the funds from your college account and lied about the car being stolen.
Once at the station, when they do the medical check, insist on documenting the damage from your father's beating, then have the asshole charged!
Luca, when you go to the police station, please bring Ari and Jordan with you....and get the ball rolling!!!
Jamie, for the love of god, accept the help offered and start healing!!!
