Man, I'm getting emotional flashbacks reading this thread. Richie, you're lucky to have such a large group supporting you through this. The only people I had when I went through my crisis was my gf's family (who I ended up moving in with when I was 19). I owe my ex's family many thanks for keeping me from going insane.
The biggest mistakes I made when I was a teenager were giving my father my bank account number, and having my car registered under his name. I threatened to arrive with a police escort to get my guitar amp back (I had the reciept). My loving father then threatened to beat the shit out of me.
I agree with storing your valuables elsewhere, but be careful who they're stored with. I lost some things to my "friends" by doing this.
Things haven't changed all that much with me and my dad. He still tries to control my life. It's much easier to ignore him when I don't live with him.
Again, I'm so fvvving sorry you're going through this.
