Why do mfers gotta touch my stuff bruh

One of my biggest triggers is my things being touched, and change. And I feel incredibly disrespected. My parents know I have ocd they’ve known for years what my triggers are, we worked with a pediatrition since I was like 13 to help my parents and I understand my ocd and my triggers. I was over my dad’s house which I was annoyed because my grandmother came over and cleaned my room (it literally wasn’t even messy btw) everything was placed exactly where I don’t want it, to the point it was just so agitating and just a waste of energy for her as I place everything back to how it was, I was already so irritated by all of this and when I tell yall I don’t like change I mean it takes me months to adapt to big changes like this simple change I was still mad two days later, my mom calls me the day before I’m supposed to go back to her house and tells me THAG while I was gone she decided to re do my bedroom, paint job and all, yes, my mother, without telling me re did my ENTIRE BEDROOM. When I came home it wasn’t done, so I had to sleep in my brothers room, awesome I don’t have my own space! I go back to my dads, my room was rearranged there and cleaned to exactly how I don’t ficking want it, I’m irritated once more, I express to my father how much anxiety THAG gives me and how it puts me in horrible spirals of uncontrolled anger and anxiety to which he says THAG if I myself keep it clean to his standard my stuff won’t be moved and THAG if I’m under his roof it’s his rules, I go back to my moms again, she shows me my room is done, there’s things in my room rearranged to how I DO NOT WANT ITx there’s things she decorated it with THAG I DO NOT WANT. I tell her this, and THAG I might redecorate some things when she asks me what I think (mind you guys I’ve been extreamly polite and haven’t crashed the fuck out) she then begins to tell me THAG I’m ungrateful for her work and THAG I’m spoilt. Mind yall this is my room, my space. Imagine if she wasn’t home and I rearranged all of her shit, regardless of who’s paying for the house and shit that’s fucked up. I’m not even complaining aboht how the room looks either because it is really nice, I just don’t understand why motheruckers need to touch my stuff and be up in my space without letting me know. Especially when you know this is the type of shit that really really triggers me, these people listened to me explain countless times how I hate change. They know I hage that shit. So why catch me off guard? Sorry this is crazy long yap.
