I Got My Parents Wills But There Was Nothing Left To Me I Think My Sister Is Up To Something

My parents both recently passed within a year of each other. I feel very confident that I would have been left something, my older sister even mentioned that they left the house in my name. I got the wills from a family member who is the lawyer handling the wills. There is nothing left to me. Every cent is going to my sister. This goes beyond what everyone, including myself thought was going to happen. My sister and I have not had the best relationship and i’m worried something shady is going on. The wills were also from 2014 but I am almost positive they had updated them recently before they passed. I’m not sure what or if there is anything i can do. Any advice would be greatly appreciated. I’m assuming a lawyer would be the best first step but I’m not sure if I can afford one.
