What can I do when my sister evicted me out of my mother's house?

I was a caregiver to my Mother. I lived with her in her home. I took care of my Mother in her home for many years. I lived with her also . She had renal failure and colon cancer. I have one sister that didnt help much. She worked full time as an Lpn. I worked until three years ago. When my mom got diagnosed with colon cancer and had surgery. I lost my.job because of all the call ins I had to miss work often to rush my mom to the er. I paid property taxes and rent while I lived there. I have no receipts to prove I.paid rent. After my.Mom died,because she had no will, I got evicted from my.home by my.sister. I was broke with no.money to afford a lawyer. And couldnt get legal aid in time for the court date. I was evicted and only.had ten days to vacate my home. My mothers home that I lived in with her. The house was sold for way less than.what is was worth because my sister as executor didnt want to.care for.the home. I am waiting for money from probate from the sale of the house. Which will not be enough money to purchase another home. What legal rights do I have to sue my.sister . I feel I am entitled to.more than half of this money. She was rarely there to help in the care of my Mother. She didnt lose her job due.ti caring for a parent. And I and my daughters are homeless after all that we have done for my Mother.Is there any hope in my.case?
