what do i do? is my mum overreacting?

i’m 22, i still live at home and last night i had come home with my friend and her boyfriend after attending a party, it was getting late and my friend and her boyfriend couldn't find a cab to take them home so i suggested that they can sleep on my couch downstairs of my house and they did. so this morning, i had told my mum that my friend was sleeping downstairs, not her boyfriend because i know my mum would flip out so my mum ends up coming downstairs an hour later to look around and she finds my friend's boyfriend fast asleep in our guest room which he must've done during the night. my mum absolutely flipped at me and told me to get out of her house, i didn't say anything and she kept calling me a liar and was so so mad at me. she hasn't spoken to me since this morning and the last thing she told me is to leave her house, im not sure what im supposed to do and i feel like if i try to speak to her, she won't hear me out. i also have to look for an apartment in the meantime and im not making a lot of money so it would really be beneficial for me to stay at home (which is why i live at home). what should i do? please help

hon Also we've had people stay over plenty times, even people I don't know particularly well and she's allowed it.
