My family is extremely toxic and I have to runaway as well. You got two ways:
1. Find a job, save up and get yourself a flat in some ghetto (since rent is cheap in there)
2. Find a job and rent a car to live out of it until you can rent (Trust me, you don't want to go to a homeless shelter)
Money is the only thing that matters ATM, cops don't give a fuck about you when you are a victim (I'm saying this, because most soy abuse sites say to keep a record of what they are doing to you, but it's bullshit. I called cops on them when they beat me up and nothing ever happened, nobody believed me). Get a copy of your ID and other important documents from them, save up as much money as you can and get ready to play their mind games, at least as long enough until you can move out. Since most likely if they will know that you want to escape they will start to stand in your way. Because I assume you are the blaming sheep for your family misfortunes like I was.
For jobs, apply for everything, lie on your resume. It's going to be tough, but construction will give you enough money, you can even build yourself up (I started digging up shit and now I'm on my way to becoming a full electrician) + most people in construction are subhumans so you will fit right in.
Get your own cellphone number, separate from your parents and use it to apply for jobs and later to contact renting. Get your mail delivered elsewhere, city hall allow you to make them as your home address (but then again every country is little different)
Finally, don't lose hope. It felt like a prison. I hated going home after work so I used to get tons of overtime and had more then one job. It's possible to live a life away from them.
Good luck. I escaped, it's possible man. This will sound bluepill as fuck but in this situation you must only try and try again until you make it work someday. I hope this helps, if you got any questions feel free to ask!
