I echo the above sentiments. You are a grown woman with a child, and you NEVER have to put up with anyone who uses or abuses you---I don't care who it is. Worse, your daughter is seeing this and will think it's normal behavior....what if she learns from your mother that it's OK to hurt you physically and emotionally, and starts doing it herself in a few years?

You MUST break this cycle of abuse and violence. You would be well within your rights to call the police and have your female parent (she is NO mother!) arrested for assault and battery. In no case should she be allowed to live with you---you ought to pack her things and kick her to the curb, literally, if that's what it takes to get this toxic, evil woman out of your life.
