Feeling hurt over my family

I’m the middle child of two of my siblings are special needs. I don’t want to come off as a brat or anything but I don’t think they treat me fairly, I’m always the one getting into trouble for small things, if I don’t clean my room or if I leave stuff around the house my mom will say it to me, but if my sister does that they will pick it up for her, she’s 22 and she’s able to do most things on her own and she chooses not too, few nights ago I was getting changed and my door was opened, my dad was walking up and I shouted don’t come up I’m getting dressed (im the only one who sleeps upstairs) and he called me a cunt, I didn’t call him names just told him to F off cause I don’t want him to see me and I heard him say I can’t deal with her and my mom is telling me to stop. Another time I got my own nail kit and I was doing them, I get gel on the floor and my mom came upstairs and stud on my lamp, I started shouting at her and my dad pushed me onto the bed and it left a mark on my arm, I am just so sick of living her, in a year I’ll be 18 so I can move out but I just can’t deal with it no more
