parenting advice

I am trying to use the model to not feel badly when I react too quickly with my kids but the reality is when my three kids start fighting, I feel angry. My thought is they are so annoying, my action is that I scream, and the result is that I feel so guilty. I do not have time in the moment to pause, and let the feeling pass. I know that my anger fuels their young souls to react the same. Which causes more guilt. Any suggestions on how to break this cycle of screaming at my kids? And stay in the model of:

c: kids fighting
thought: this is annoying but this is what kids do
feeling: neutral (i wish) all kids do it
action: don’t scream
r: don’t feel guilty.

Kids fighting is such a trigger!
