How can an aunt take the entire family trust?

My grandmother owned five acres. My mother had a home on the property also. My aunt sold the entire property including my mother’s house and my grandmother for 1.3 mil. They paid cash for a new home and let my mom live in it but listed it as a rental I guess for tax purposes and creditor protection? My aunt bought a new home but instead of paying cash, they have a mortgage on theirs. My mom invested $250000 dollars and my grandma was 94 years old when they set up the trust it was supposed to be split 3 ways because there was 3 daughters. I was informed today from my aunt that she took the full million for herself. My mom left me the house in her will that she assumed was hers n supposed to be hers, and I was told I will not be getting the house and that the house is going to be sold. I've taken care of my mother for years and quit my job of $50000 a year to take care of my mother. I've spent hundreds of dollars remodeling and building waterfalls for my mother and I had zero help. I had to do everything for her except physically feed her. I gave up a lot for the love I have for my mom. And I was told that was my daughterly duties. No it was my honor not my obligation. I just don't see how she can get away with giving my mother next to nothing or nothing and my mother not having a say about what her wishes were. And invest and give up her other home and have nothing in return. I am in shock and so disturbed by all this. I am sick to my stomach. What can be done! There should be a law and criminal punishment for this. Please tell me something can be done!
