mother accusing me of being “pissed off” at her all the time

it's nearly everyday she accuses me of being angry, being pissed off and upset with her. it can be the most basic interaction and she's like "Oh, I pissed you off" when I'm actually just fine. Then she goes and sulks in the corner. She's also accusing me of always giving her "that look" and i have absolutely no idea what it looks like because i never purposefully give her rude facial expressions. also not quite on the same topic but anyone else's mom throw a tantrum like weekly? because she will stomp and thrash around like a fussy toddler, fully wailing and throwing her body around and throw things. i came downstairs one day to our food all over the floor and just blank-faced her, grabbed what i needed and went back upstairs as she stared at me and waited for me to pay attention. i'm exhausted lol. she can't handle anyone else having a bad attitude and then goes around accusing everyone of never letting her have emotions or externalize her emotions when it's the opposite.
