I need help! PERSONAL MATTER

Theres this crazy psychotic wench in my dad's house (2nd wife) abusing me (1st wife's son) with verbal assault and yapping about how she wants to throw me out of the house that MY DAD paid the rent for.
I know that she's powerless but her crazy voice sounds psychotic and annoying at the same time plus i worry that her frustration may lead her to do some disastrous things to my belongings

My posession:
I only own a BED and a PC

HOW IT STARTED
I've misinformed the driver to pick her daughter up(2nd wife's daughter) at a later time(she got picked up late), that's how she drove herself into this mad state by walking into the door from work and straight out YELL in my face "why did you misinform her driver, has video games been screwing up with your head?", ofc i responded with force, saying its not a big deal, everyone makes mistakes at one point then close it up with the sorry, yet this foo wants to continue toying with me for being so aggresive, yet failed to realize that I'm reacting based on how she approached me.

I understood that there are minor faults here and there but really all of this aggression isn't really
neccessary, I do not wish to anticipate a meaningless discussion with her in which can aggrevate the situation
are there any possible resolution in which i can diminish the aftermath(as of now?)

UPDATE:
She now accused me of committing the act as I were to manipulate the driver....
Seriously...
And I've lived over 10++years in this house, NOT ONCE have I've been accused of doing such
