Emotionally abuse and legal rights of daughter in law

I'm an only daughter of my parents and married for 4 years. I've had some issues with my mother in law (she continuously gossips about me to father in law, complains about me to my husband, lies and manipulates) and my husband supports his parents denying everything they do against me. My mother is terminally ill and they don't allow my mother to stay with us (office provided residence to me). I'm currently staying with my mother in her house, with my daughter, as my mother is not comfortable staying alone. Now my husband and in-laws accuse me of keeping their child/grandchild away from them but I've never denied them to visit her or take her with them for a few days. Can the behaviour of my in-laws and husband be called emotionally abusive and what are my legal rights in this situation?
