my dad told me that he wishes he was dead

I dont know what to do. Everything is falling apart.

For context I woke up and hear yelling between my brother and dad. I didnt want to go there because i didn’t want to be yelled at too.
Then when they stopped I went to them. I told my dad that i will eat something and then start to help with cleaning up.

He however got mad at my brother again and my brother left so he started yelling at me. Telling me how he wishes he was dead instead,
I don’t know what to do. He is just yelling at my mom too.

I dont know what to do. I dont want to be here anymore with them too and just die
