Eldest sister hates mother. a lot

Well, it goes as far back as i can remember.. we are 3 sisters 5 year gab between each no boys and two alive parents.. i know they do their best but my sis doesnt think so.. my mom has a really pushy side which might have started it, she tends to be in everyone's buisness and when irked to a digree she just losses it even if it was something insignefecent like how when i was 10 i took my older sis' hat to a school party and lost it somehow, mother had me walk back there 3-4 times in the scorching heat just 2 look for it plus other punishments.. even skipping a meal could be such bothersome bcuz she is so pusshy, she will never take no for an answer so imagine how she is with bigger things.. i know she might have good intentions but taking my phone away for 3 weeks was too much.. she gave it back only bcuz i promised i would stop ( im 18 and its summer, sue me) + college was starting. my sis doesnt only "hate" mom but also dad, even tho he is much older than mom and isnt as involved as mom.. i use the term hate bcuz she doesnt want to talk to them most of time, and her entire mood shifts the sec she walks in home, like we are all the bane of her life.. she often criticizes every little thing and is very unuseful and selfish, like how we were all in the same car recently litrally lost looking for a spicific building bcuz none of our phones could use google maps and hers was able to, but she chose to not help at all.. she has anger issues and deals with everything with yelling even if it was stupid, like when my youngest sis couldnt fix her bed right.. one minute we're all laughing and the other she goes crazy and wouldnt let anyone in her room... she even screams at mom.. i hope someone could advise us on how to deal with this, my little sis and i are gonna lose our sh*t if this goes any longer
