I am so sorry that you are dealing with this. If it is possible, moving out and blocking communication with your family members for awhile will be nothing but beneficial. No matter if you stay or leave your family, setting some firm emotional and physical boundaries will prevent you from becoming a walking doormat. As already mentioned here, if this escalates to something physical, call the authorities. You have every right to protect yourself and your dignity, while refusing contact with people who continually make you uncomfortable.
