My grandma died, the will was changed but I'm still on the checking account, how do I protect myself?

Ok, so I think I told you guys that I'm from Indiana but am working as a live in caretaker in NY. Before, I cared for my grandma for 10 years. The house and property was originally willed to me. Since I've been here, I've been paying her taxes, giving her $500+ per month for the bills. Even up to the day before she died she was anxious for my patient to pass so I could go home. I just found out that she changed her will in March leaving everything to my mom and brother (both drug addicts). I was obviously shocked but I know that they were probably wearing her down. I'm less upset about the way it is and more upset that she didn't tell me and kept taking my money instead of letting me keep it since she knew I was going to be homeless. I'm trying to make peace for myself but dang, that's crazy. Anyway, the more pressing issue is that I'm on her checking account and I'm so scared of them overdrawing it and the auto pays attached. I can't communicate with them and I'm not sure what the bank can do. I tried logging into the auto accounts but the pw and recovery emails are changed. I can't afford to be liable and I now need all my money and can't afford to be paying lawyers. Any advice or links? I tried research but only see info about the money left being mine. I don't care about that, I just don't want to owe if they do shady stuff. It is so sordid. My grandma is stuck in the funeral home bc none of her kids (including the benefactor) will contribute to the funeral. If she only knew how much of a nightmare she caused.
