AITA for really screaming at my sister after she had been treating me poorly and ignoring me?

My sister has been staying with my mother and I for a while now. She had a place of her own but she’s had to move out, she is staying with us until I think either next week or the week after. Since she is a guest I have been told to give my room to her, I’m letting her stay in my room but now it is an absolute mess. I haven’t said anything about it because she will get mad. However, yesterday I had a friend over we had a really good day and took some videos. When my friend left I was happy and wanted to show my sister so I went to her and started a conversation, asked how she was but she was being really dry and had short answers. She suddenly started talking about how I never look after our mum, which is not true, and she just started listing all my flaws. Now for some reason I felt so angry and then I shouted at her and we started arguing. My mother came in the room and asked what had happened, neither of them let me talk. My sister had really gotten up in my space and tried to hit me and it was all just very overwhelming. After that we made up, or so I thought. The next day I had gone to talk to her and she told me “you obviously don’t want me here so I’m going to stay out of your way”. It’s been a few hours I’ve tried talking to her which results in her kissing her teeth and retreating back to MY room. I honestly have no idea what to do, I just want her to spend time with me.
