AITAH sibling won’t get out of my room

So I’m a teen yk. I have a gaming console. I got it for Christmas a year ago. I use it occasionally. Watching movies/shows, playing games, yada yada, etc. Well, these past few weeks. It’s been dominated by my sibling. He practically lives in my room. I can’t get him to leave, always on my bed. Sometimes he brings my cousins over and will sit in my room. They throw trash everywhere. They have broken my things. I’m honestly over it. He also has very loud friends. I might be a Karen for complaining but it’s honestly annoying. I don’t ever get any time alone in my room besides when he’s gone. And I don’t have a big room either. I’m the type who likes to be alone and do things that don’t involve anyone else. Don’t get me wrong I love being around people. But when I’m home. I like to relax and breathe. But u can’t when he’s around.

For example,

I was on my phone in my bed. Then he came in. I calmly told him “please not tonight. I don’t want to hear either of u yell. You’ve been in my room all day for the past week or two. I want some peace for a little.” He said “well u can’t tell me what to do. Mom said I can”.

I gen wanted to pull my hair out. He got on the game. Used my password and account. (I never gave it to him. Someone else did) I sighed rolling my eyes. And he got on his game with his friend. Both he and his friend were practically screaming at each other through the screen. They were playing Fortnite so I understand it gets stressful because I play to yk. But they were being so loud I had to leave the room to not yell. I had a headache. I feel like I’m being rage baited…💀💔

but anyways I’ve had to sleep on the couch because he was up til 3-4 AM screaming. It’s become a daily thing. I usually tell him to leave, not today but he just ignores me. But I’ve tried to tell my parents, express my concerns and feelings but it’s always. “If it bothers you that much, move it into the living room”. But it’s my console?…

Shouldn’t he respect that it’s my space?..

(He used to have devices and other things but he broke my parents’ trust .)

(lmk if you have any questions)

I might be the one in the wrong so if I am just tell me. Be completely honest.
