So sorry for you to be so lost and without guidance. Like is tough and dangerous for the young and vulnerable. Without an adult to advocate on your behalf you have little recourse but to document and make a formal complaint, whether proper action can be taken or not. But your real issue is to find a safe place from which to slowly build from and that starts with the local health and human services office in your community.
If I knew what state or county you are in I can look it up, or you can yourself. Not sure your age at this time but child protective services can also be a good place to start getting help, or referrals to help.
Good luck and sorry for your misfortune.

Runaway would be more accurate. As I cannot see you going through the court system without a child advocate or nowhere to go and no means of support.
