Loss and family drama

My sister passed away last week and I had only just started talking to her and my other sister again after years of avoiding the family fighting. I knew that coming here to mourn would be filled with the same drama as when we weren't grieving. My mom wants to blame others, fight with us, and force her way of doing things on is, and my other sister is similar to mom. I'm in the middle and alone now. There's no other family members to help or understand. I flew down to be there for my family and now all I want to do is run back home.
