Is it normal to have your mom and older sister fist fight
I'm a young teenage girl, and my mom and older sister who is 17 always fight. Today they got into another fist fight and wrestled and I don't know if normal families do this and stuff. My mom slammed her phone and the ground and it broke, my sister told her to rot in hell, they scream at eachother, my sister cries hysterically, and says she's going to kill herself. Please tell me if this is normal. I'm tired of being the family counselor because after they both come to me and tell me how horrible eachother is and I'm really tired of it. Then I have to try and talk my sister out of killing herself. It isn't fair to me and I don't know if other families go through this too.
