I have returned to India with my daughter after living in Dubai for a long time. We are a matriarchal joint family. My sister’s family and my parents all live together. I find my parents prefer my sister and her kids to me and my daughter. My sister also ignores me and my daughter most of the time. Since I cannot move out on my own immediately, how can I deal with the situation?

As you have said that you cannot move immediately, only option you have is to accept their attitude. You cannot teach any one to respect you. Once you accept their attitude and stop longing for change in that, you will be comfortable for time being.
