Can I just yell back at my mom and older sister?
Do you want to say anything about why you want to yell at your mom and sister?
One time my mom threatened me if I wouldn't listen better
It sounds like there are some problems with getting along in your family. It's better if you could all sit down and have a talk about the issue instead of just yelling at each other. You might be able to find a solution by talking it over.
They make me so mad. They need to listen to what I to make me feel better.
I agree with you that they need to listen to you, but you also need to listen to them. I'm sure you want to live in a more peaceful household. The best way to get to that point is for all of you to agree to sit down and have a calm conversation about how to fix things.
