Am i crazy? Or is my family a teigger for me?

So i moved in with my sister about a month ago. I was in a bad situation with my mother so i moved because i was constantly going down a path i didnt want to be on. So my sister has a 17 year old and a 10 year old. I love them to death but they are tornadoes when it comes to making messes and never cleaning up after themselves. Also, they can be really fking disrepectful to me occasionally. And right now im not really paying rent because i dont have the money. Im Saving up.

So ive been cleaning constantly. The first two weeks i cleaned the same messes everyday twice a day! then a week ago i get yelled at because im not helping out. Just because i stopped cleaning for a few days and my sister had too do it. Take it. Before i moved in she and her husband did it and rarely made her kids help.

They are spoiled brats.

They really are.

My mother did the same thing to me. Except she would always make messes then blame me and so on and so forth. Her boyfriend did it too. My mother is crazy and manipulative also.

so i moved in with my sister and shes so cynical its annoying.

My sister and i have a strained relationship due to the past. And our mother adandoning her and her blaming me for the longest time. Then she turned the blame to my father.

So anyway.

She asked me a few days ago to do the dishes and i did. Then today i did more dishes. So we did for a longwhile today and she asked me to finsihes the rest. But i was gonna finish them in the morning and she is just like "I asked you to finish the dishes two days ago! Stop acting like a child!"

Frankly, i know this may sound whiny but im just trying to get an outside opinion.

Idk what it is but when i live with my family. I always turn into the maid. And i grt cleaning because i dont pay rent right now but im frankly tired of conatantly cleaning the same Messes everyday twice a day. Idk if im self sabotaging or what. My familt is so dyafunctional and they just dont underatand me as a peraon. They never let me make my own descisions. They tell me i need to so this and that and act like this. Be this way. But i just wanna be my own fking person. Everytime i live with family no matter what family i go back to my teenage mind set of being submissive and just surviving. And my sister is never wrong about anything. I cant talk to her about shit about my life because she always has it harder than me.

In youe opinion. Am i acting like a child or is my family a trigger for me?
