My Mother-in-law hates me and my husband. Right from the day one she has been rude to me.?

She sweet talks my husband. She has other kids and prioritizes them over him. I feel vey bad about this. Now that we have a child, She hates our child as well. She didn't do anything for the baby when she came to visit us. She slept and relaxed herself. I had to do all the work. My husband is scared of her and even when she doesn't care for him, She acts as though she loves my husband very much. Right after our marriage she told bad things about me and she ruined our wedding. We didn't lead a happy life for the past 4 years. Now she went off without helping us with our child. But even now she calls and asks how we are doing all the time. I get pissed because of her attitude. Also she makes her other kids call us and tortures my husband. My husband won't open his mouth and she takes advantage of that. If at all he asks(very very rarely that too politely), She will cry and make us look bad. Her crying is her only weapon. I really don't know waht to do?. Please help. I haven't slept after I got married because of my in-laws. If i talk my MIL says that " Look at her talk. Control her and also" you are dancing to your wife". My FIL dance for everything my MIL says. I have no clue how to get out of this. I love my husband very much and I don't want to leave him. My husband is very nice but he doesn't have the guts to talk to my MIL and support me or my child. Help pls as soon as possible...................
