Firstly I want to say Im sorry to hear of the situation you are in.
I echo what others have said. It seems it would be best to try to save money to eventually move out whenever possible. Untill then, find the opportunitites that present themselves to you, to find freedom, solace and some sort of personal happiness. Even if its something small like going out somewhere with a friend, away from family, as yourself. Things like things to build you up and bring you through each day.
Moving out does sound like the best thing. I had to move out at 18 because of all this I was going through. While my Mum and siblings were not physicaly abusive, or abusive at all (not this part of my family atleast) they made things impossible for me, my depression worse, and I had no privacy. You need your privacy and space. You and you Father need space away from eachother.
Years later, me and my family are now so much closer. The distance helps us. One, for me to be able to grow and live, and two, for them to accept me on their terms, see my happiness, and for me to try to help them understand my side, from a distance.
I hope all goes well for you and,
Good luck with the job tomorrow!! I hope you get it
