Torture & harrasment

I got married on 7th march 2018 in temple. I hv no issue with my husband,he cares for me but still for long 1.5 years I stayed in my mother house bcoz my mother-in-law, brother-in-law,sister-in-law all everytime tortures me do harrasment, they have crossed all their limits. But recently 2 months ago my mother expired & after this incident in my life I again tried to settle down in my in-laws house but again they are having the same behavior especially my mother-in-law. What should I do? In this 2 years of journey every single moment I have tried to win their hearts but they are very cruel. I belong from a poor family, my alone father & 3 younger unmarried small sisters cannot help me in any manner. Where should I go & what will help me bcoz I can't afford legal expenses. My husband earning is not such that he can afford any other house & this house is in the name of my grandfather-in-law. My mother-in-law threaten us that she will file a false Senior Citizen Case against me & my husband to put us out of the house. How can i teach them lesson to stop all this from my life? Please Kindly guide me ?, please help me.. Thank you...
