What do you do if your mothers angry and you're also angry?

Take time off, a break from eachother for a bit

depending on the situation, it might be best to step away from the conflict and cool down in your room or something. once you've calmed down, depending on what it is, you can go back and talk to her more reasonably when you're ready

she would yell at me, i would yell back, she would hit me and yell more, i would go silent not saying anything the rest of the day
