she snores and makes me a bigger b@&$

Sorry i have ti rant a bit😩😭Im 11 weeks pregnant and i share my room with a friend they dont know im pregnnt yet . Shes been curious why im always sleeping but yet shes so inconsiderate! She works overnights so during the week when she gets ready to work she makes so much noise turns on the tv and leaves everything on when she leaves . On weekends she snores so loud so i put on music and once i fall asleep she turns it off without asking me and then wakes up around 6 so i dont get to sleep or rest much before my work week again... im holding everything in and the person that knows in the house tells me to tell her im pregnant but im obviously not ready to tell anyone... how do you ladies deal with stuff like this i have a really bad attitude right now i just prefer to stay quiet than to speak up and have tension in the house!
