Why won't no one respect me?

me 20F and my sister is 17F almost 18. It seems as If no one in my house doesn't respect me or simply I am not favored.

My sister has gotten a new dog recently and she has not tooken care of it once. I've took her on walks the whole week we got her. and today that I refused to take it I was targeted obv even though my sister was home just playing video games.

a recent argument is when my sister lost her makeup and made a huge deal over it for the whole day. she came into my room and started throwing all of my art and belongings looking for it. I told her to stop and pick up what she threw but just stormed off.. My mom calls a bit after asking if she found her makeup. I told her I didn't care because my stuff literally got destroyed and she just kept asking for the makeup? my boyfriend even told me that, that is how she will respond and then my mom's boyfriend said that what she was doing was wrong. She hung up after that.

Even if I argue back I'm not respected at all and they all use personal things against me in arguments. I'm not big with drama and I would just like to know how to stop this. I cannot move out I'm stuck here so don't suggest moving out as an option
