Emotional harassment by in-laws

I got married on 2011. From the day one of my marriage till date, my in-laws have not accepted me as their family member. They keep me away from anything and everything. Even from the household work. If I do any work, my mother-in-law finds mistakes and tonts me. If I don't do anything, then also she tonts me. I won't be informed about anything happens in the house or in the family or in the relationship. They don't talk to me, they always keep there rooms door shut and have all talks and discussions. If all the members are talking in common hall area and if I enter, they immediately stop talking (be it any topic) and leave the area one after the other. I am not even allowed to cook my food if I am hungry, I am neither allowed to get any eatable from outside for myself. My husband knows it all but he supports his family, for him also am not part of that "family". I had many discussions, arguments and fights with my husband. Unfortunately he is not doing anything. He is also not ready to leave his parents and live in a separate house. he always expects me to adjust and have patience!! My in-laws extracts all the money from my husband and yet he pays house loan and other misselanious expenses. All my dreams and wishes are unfulfilled because of lack of money. With all this problems I have got health issues and due to which we have no children yet. Being an working women I am so helpless and I don't know what to do. Please help me and assist me.
