I don't want to have a sister

I can't stand this anymoremy parents' attitude towards me. I'm 15 years old, I have a younger onesister Nastya, who is five years old. We live in a two-room apartment, and until now my sister slept in my parents’ room, but recentlyMom said that now Nastya and I will have a common room.

I was against it and immediately warned my parents that I would not be in the same room with her, because she was still small and would disturb me. But when I came back from school one day, I saw that my mother had moved my sister’s things to my room and had already laid them out in the closet. I began to be indignant, and my mother called me an ungrateful, selfish person. How, one wonders, will I do my homework in the evenings now when Nastya comes home from kindergarten?

Now I almost have toclean the room every day , because my sister throws everything around, her toys, her clothes, even pulled mine out of the closet. He eats cookies in the room, which irritates me very much, but my mother pretends that everything is fine and also says that test-antibiotic.com I was the same at her age and they also cleaned up after me. But what does this have to do with me, they are her parents, not me? Why doesn't anyone understand me or want to listen to me?

I want to leave home completely, but there’s simply nowhere, I only have one grandmother, and she lives in another city. There is no one to even complain to. I didn’t find any support from my dad either, he says: “figure it out yourself” or “mom knows better what to do.” I envy my friend, who is alone in the family, so I wish it were the same for me. Why did my parents decide to have another child and now give it to me? When I asked to buy me a cat, my mother said that I needed to clean up after him, and now I have to do the same after my sister. What should I do, how can I convince my mother to make my sister come back to their room?
