My mother is warning me that she will kill herself and blame me for it. she put a condition, I have to vacate house.

Everyone here who were sympathetic to my mother, should tell what to do now?

My mother is illiterate.  how can she tell such things? surely, my sister and brother-in-law are behind it.

Is there any thing in law to help me or even now I am helpless?

thanks
