Sleeping In bed with someone who’s just loud asf

Her voice is loud asf at night and she laughs like she’s singing soprano… AND SHE PUTS HER BRIGHTNESS ALL THE WAY UP ON HER PHONE. Obvs since I’m a sleepy girl I usually sleep earlier then her - whenever I do try to sleep and she sees that she coincidentally scrolls on tt and screams laughing like bro pleeeeeaaaaaaseee stfu pleeeeeeaaassw I’m begging you and when I tell her to do so she just ignores me?!!!! Sometimes i wish I was dead so I don’t have to hear her voice at night Ive literally cried about this to her and she thinks I’m overreacting I’m gonna kms. And for some godforsaken fuckinf reason she gets up at like 6-7 in the weekends and talks to her self LOUDLY WITH HER OUTSIDE VOICE WTFFFF. I literally scream at her to stfu and she just ignores it help me why can’t I wake up at 10:00am feeling refreshed nd shit why do I have to wake up w a migraine and crying my eyes out at 7:00am on a Saturday
