Holy shit, CB.
Well to be honest, here's what I would do:
1) Beg the fucking shit out of your parents. Get 2 jobs, and basically kiss their ass until they cave. Fuck pride and dignity, you have to find a place to live. If they let you come back, work 24/7 until you have enough money so you can move out.
2) Stay with friends, family, or people from your wrestling school. As TM said, you'll have to find a place, because the cold weather is moving in soon.
3) Live in your car. While it may not be the safest thing to do, it's better than freezing to death. Take a couple of blankets from home, and live in your car. Get knives, guns, metal baseball bats, etc. for protection. Look for work in the day, and at night, cover your windows, lock your doors, and park in a safe place. It won't be comfortable, but it will give you a place to stay until you get back on your feet.
Hopefully I've helped, and you will be in my prayers.
