you sound like your under the legal age of 18;if this is the case tell your parents about your concerns;they will know how to handle it.if your friend is over 18 they can leave home if they can find someone trustworthy too stay with.if they have sisters and brothers they can ask faimly court to grant them legal custory of any minor children.I agree with the above tell someone in authority what's going on,before someone gets badly injuryed.keep us posted;my prayers are with you and your friend.
