Harassment from mother in law

I am married ,it’s been 5 years .from last 5years I faced a lot from mother in law and their family .It’s a joint family . In early years of marriage ,my mother in law demanded so many things from my parents and scolding me for my dark skin complexion.after few years I got pregnancy issues I got several operations after all those efforts I got pregnant now I am mother of two kids one boy and one girl .after all this still she gives me mental torcher. Every day . Now I am scared she will take my kids also from me ?. I don’t have any support from my husband. He doesn’t even care of my bills , I am working so I was paying my bills myself . He blames me whenever the fights happens in between me and his mother .for example fights and arguments can happen on anything ,in my case I have to listen to her on everything what I have to wear Also-for example I have to wear saree or salwar also will decided by her ,if I wish to buy gold from my salary I have to take her permission first,not by my choice .especially on menstrual cycle she treats me like untouchable object , i should sleep on floor ..Should I have to keep tolerating all this for my kids . Do I have any rights to fight with them ? After getting married I lost my mental confidence and physical confidence and my carrier ,I don’t know which path to choose . I don’t have any hope that my husband will support me in any ways .
