I'm going to get at my mom after repeatedly telling her to stop
Why would you get at your mom? You should try to fix things before getting into a fight.
I'm fed up with her shit, she is antagonizing me
You should avoid blowing up on your mom because of how she treats you. Tell her how you feel in a calm way and if it continues you can then make a decision on how to handle your relationship.
She keeps apologizing for her behavior towards me, but it feels fake. I am going to jump her shit for this.
You may not like the way your mom treats you, but acting hostile towards her won't solve anything. Try patient dialogue and see if that doesn't work better for you.
