I kinda hate my sister

I need to vent y’all. I was gone from my house for a few days and when I came back home today, my sister had completely taken over my room, wrecked my closet, given my plushies TO OUR DOGS, spilt food all over my bed.
And it’s not like she’s a toddler or something anymore. She’s already 12. She also constantly hits me, I don’t hit back thinking “she’s just a kid she’ll change” but it’s just getting worse. I just really want her gone.
