I Wish I Knew Then What I Know Now

So pretty much I've been living without my parents support since I was 14 when I got my first part time job, I recently (kind of recently) moved out of theirs exactly one year ago because I didn't want to live with them. Since then the day I moved out I was 17 years of age and in year 11 at school. Now I'm in year 12. I've moved over six times and I live in a different state of the country than a posed to my parents. In order for me to get my independence allowance I needed their lease copy to prove that I wasn't living with them so I got centre link to send them a letter regarding the following. I called my mother telling her I needed a copy of the lease and she was willing to send it to me. Exactly 3 days after that phone call I had with her which is a week from today I get a very abusive phone call off my father and him telling me that I'm not his problem and that I was a mistake and I ruined his and my mother's life. Basically both of my parents have used me for money so what he was saying was bull shot. I hung up on him because honestly I couldn't get through to him and I blocked his and my mums number and basically I have no family anymore. I've been their for my parents and they aren't their for me. The thinges is i was and am the only one who actually put in the effort to keep in contact. My mum called me yesterday and it went straight to voice mail because I blocked her number. I honestly want nothing to do with them anymore. They have treated me horribly all of my life. My mum use to hit me when I lived with them and my dad threatened all the time. I'm in year 12 now and I live with my best friend and her family I am basically living out of boxes and plus I'm working long hours just to survive. I honestly am losing hope in my life at the moment. I've tried everything.
