My life is in danger

20f my grandmother recently passed away and left a house for me. My aunt and mother are eyeing for the house, my mother will only let me stay if I give her 80 percent of the money after selling the house and my aunt is asking my mom to send me to her place to stay. My aunt is planning to entangle me up with his son somehow and get me married to him so they get the property. What's the best course of action I can take , ig I don't do anything either I will be sent to my aunts place or will be dead.

Edit : thanks for all your advice and suggestions and sorry for not responding ( i was dealing with health issues and was shifting to another relatives place who was close to my Nani and better than rest of my family in terms of trusting her with my life ). I will be getting back at my lawyer and transferring the house to my and making a will simultaneously.

There ain't any family member I fully trust after this and many more incidents which have happened in past so I'm planning to make my close family friend as power of attorney who won't rat out to my family, as well as writing a nc against my mom would cause me more damage than advantage as the police in near by jurisdiction has pretty good connections with my mom.

The whole point is my mom wanting to get control over me as she knows once I leave the city there ain't a way I'm coming back( as I have funds and all resources) to this place and the place I'm planning to go to college is where my aunt lives and she has brainwashed my mom into thinking if I stay with them she( mom) would always have control over me. At this moment all I can do his soothe my mom's ego and give a false hope while preparing the funds to leave. Once again thanks for all your inputs and definitely all your suggestions has helped to get at this decision. I'm not planning sell this house untile all my other options are out of picture , this is the last memory i have of her
