Mentally harassment by mother in law

Now more that 1 yr is completed for my Marriage. I am suffering from mental harassment by my mother in law. Most of the time she talks rudely with me, most of time taunt me and I feel depressed. This all happens when my fil & husband not around. So I tried to avoid her specially when I am alone. I had miscarriage of 3 month because of mentally stress, I expected at least emotionally support me during that time. But nothing. My husband on my side., support me. He said ignore her. But I want at least she will know it's emotionally hurt when she uses harsh word. Sometimes it's unbearable for me. I don't know what to do.. She treat me as a servant only . She feels that daughter in law have to do every work at home i m also trying to everything but she is satisfied with anything. In fact she ia not doing any work only sitting in front of the Tv. If a single was not wake up due to health issues that time time she is creating lots of dramas.. auch a mentally stress she giving. Because of her only i don't hv any interest about my married life. I just want to finish my life . Plz suggest me what should I do?
