Dream About Fighting Drunk Sister

I dreamt I was fighting with my drunk sister. I was beating her up and she kept talking shit. Then my dad and stepmom walked in when I kicked her hard and told them she was drunk and saying ugly shit. My dad walked up and my stepmom was mad at me. I needed to be driven to school and since that happened nobody would drive me. I ended up getting my stuff to move out and walking to school. I had somewhere I felt but don’t remember. Then when I got to the other place I figured out I left my phone behind at their house.
