Should I tell her?

My sister came in town with her two boys at the start of summer and we thought her kids would only be with us for 2 weeks (this was in May). SHE IS STILL HERE AND ITS AUGUST. I dint mean to sound rude but she totally ruined my summer,I’m glad they’re here but I only have two more summers before I graduate and I want to spend them doing what I want and not worrying about what she thinks.it wouldn’t be a big deal if she wasn’t so adement about everything being her way. I mean at the very beginning she gave me a 30 minute lecture about why we should go to publix instead of whinn Dixie as if it was my decision anyways. And anything I have that doesn’t come from the thrift store she has a problem with for example she went off on me because I have an Apple Watch and went on to explain how unnecessary it was. She always puts me down on everything and she changes literally everything in our house and I’m like “bitch this isn’t even your house so stop changing it”.she definitely doesn’t hesitate to point out my every flaw so everyone knows.i don’t know what to do, I feel like if I tell her she will get mad and make my life a living hell and if I say what I want to say it makes me like the worst sister ever (even though she makes it clear I’m her least favorite sister she literally said it to my face). What should I do? Do I talk to her or just ride it out?
