If it is at all possible for you to leave, please consider doing so. The family situation you describe is not safe for you. If your school counselor is not around, find out how you can make an appointment at a specific time, and tell the counselor what is going on at your house, and explain how important to you it is for you to graduate as soon as possible. You have work experience (working at your father's office is still working), so be proud of your work experience and if you cannot find paid work, do volunteer work (at your local hospital, library, animal shelter, school -- these are places that often welcome volunteers). Your brother, mother and sister threatening you and battering--pushing, slapping, hitting-- you are committing a crime. Take a few moments to find out if there are battered women's shelters in your town and what the rules are for admittance. Just because there is a blood tie does not mean you have to accept abuse.
