I communicated my sensitivity around feeling left out to my housemates and got the silent treatment for weeks now

So this has been going on for 3 weeks now. context: I (20F) live in a co-house where I've lived with one person (22F) for 1,5 years, then in juli/august the rooms and second living got renovated and now two people (23F and 20F) live downstairs too.

I went on vacation in the beginning of September, during the vacation (august and July) I was often away (living life and working). During my vacation (first week of September), my housemates were often communicating in the groupchat between their 3, not necessarily about house-related stuff, but they were just doing a lot of activities together and making lots of jokes and sharing all these memes of the each other and photos and videos of the 3 of them. To every message I sent, there was almost no reply and they would continue to interact between the 3 of them. I was happy for them, also because the housemate I was living with for so long at first didn't think well of them and said she couldn't truly trust them, because one of the housemates has talked a lot behind my back or the other new housemate back to tell things that disturbed her instead of addressing the person directly (the two new housemates often in the beginning just would trauma dump all their problems and all their problems with their 'bad' friends. So at first our both impressions were not that good of them. I used to get along with the two new ones tho, I just noticed they're just people that are quite different than me emotionally-wise and communication-wise. (which is also the case with the housemate I was living with for the past year.

This changed while I was away apparently, now the 3 of them are closer and have more fun together. Before I left for my trip I noticed that the housemate I was living with was a bit more dry. I had asked her if I could borrow her small luggage because mine was a tad bit too big, and she just responded 'I need it for myself', I was like could we maybe swap for just a week (since she does her laundry with it), and she didn't respond at all. (I have struggled with her communication-style since the beginning) when there's something wrong she just doesn't acknowledge me anymore or answers 'mm' or if I'm lucky 'sure' when I try to speak to her. doesn't say hi anymore, basically gives me the silent treatment. I am quite hypersensitive so when there's something up with someone I sense it deeply in my body, so I tried to explain to her that her just shutting down while she spoke to me normally before does something to me, and that I'm here for her also is she needs something.

in the beginning we also had this altercation were we decided to go to the city together and she was sooooo dry and I felt soooo stressed out about it. when I was trying to tell her that I'd like to separate ways and find each other at home, she was just ike 'sure' didn't look at me, turned around and stepped away. I was supposed to go the a festival with her and the then "future" housemates, but I just felt so weird in her presence that I didn't want to go. I tried to put boundaries that I didn't want to communicate like this and that she was so off to me the whole day and always expects me to get over that. she then got soooo mad and was screaming 'what's your problem, what's your problem and slammed my door and the bathroom door while I was inside 3 times.

after this she wrote me a letter that we should just get over this and have fun at the festival because we had been looking forward to this, and that she would address this after the festival (she never did, and when I tried it was brushed of)

THE CURRENT SITUATION NOW IS:

I came back from my vacation the first Friday of September and was already a bit stressed out about not the place I would take in the co-housing since I didn't feel like the contact was nice during the week. I come back, (we have two living rooms, the rule Is that she asks if it's okay for every one to hang upstairs since I get overstimulated fast) but everyone was there when I told them I would be back from vacation and they were cooking together and would do all these activities together but there wasn't no invitation at all. They ask me 2-3 questions about my trip, but I just sense such a different energy towards me. I wanted to cook but one of the girls from downstairs was cooking too, she gets frustrated and is like 'this is too chaotic' so she tells the other housemate that she's gonna go downstairs, when the housemate that I had been living with comes back she also tells her yeah I couldn't bare to cook here with two so I cooked downstairs. but like never! addressed me? When I talked the responses of one of the housemates from downstairs and the one I had lived with the whole time were so dry and they kept interacting between the three of them. They were watching videos together that they had been watching for the last week and I was soooo stressed out that I put myself in the couch but was visibly more down, then they start to dance and make so much noise until I tell them that my head is starting to hurt, so they don't response but just between them three are like let's go downstairs and nobody says bye or looks at me until I say goodnight.

in the morning after I sent a message stating that I was a bit nervous yesterday because the real-life interactions feel exactly like this group-chat. where I'm not really there. and that if there's anything I hope they feel safe enough to always tell me. I also tell them that there's a mass celebration for my mom and that I won't be home until the evening and the next day because of that. I come back home with my sister and when we come in one of the housemates from downstairs is cleaning the bathroom and looks up 3 times, sighs and raises her eyebrows while looking at us. my sister gets closer to go upstairs and she keeps looking at us weirdly until my sister is like what's up, why are you looking at us that way? and then she's like ummm ooh yeah I don't have my glasses, she then says hi to my sister a bit nervous and asks me how day was (something she never asks) they all skip my message until someone from downstairs says 'um no there's nothing wrong but we can talk about this with 4) I answer that I don't have the room to have a groupconvo but that if something arises you can speak to me 1 on 1.

The next day (Sunday) I see the girl that I was living with, she doesn't say hi, I ask if she read my message she answers' umm idk, yeah I think so' I ask if there's nothing she wants to share, she's like 'not over text' I'm just like okay? in my head

Monday comes, we have a visit for my room at 7 (I WILL BE MOVING OUT IN A FEW DAYS). I arrive at 6 and the living room and kitchen are MESSY, I ask her to come clean because the visit will almost be there. She comes downstairs with one of the other housemates and is visibly irritated, she used up one of my plastics that I use for my freezer and I ask her if those are mine she answers 'mm' not even looking at me, I ask her if she could by a new one she answers 'sure', meanwhile she's speaking all giggly with the other housemate. I'm like is there a reason why you are so dry? she's answers yeah with all the stuff from you from the past days I'm sick of you this isn't the first time you make a drama out of nothing. I'm like I was just sharing how I experienced the co-house, she answers with a smirk that I make nothing out of something that they don't see a problem so that I'm the problem basically. I respond that I was just trying to explain that these are just my feelings, and she just responds in this sooo passive-aggressive, mean-girl, mocking, childish way the whole time. I ask her what she gains from speaking to me that way and that if something is bothering her she can tell me, she's like you didn't say hi when my sister was here, mind you I was busy discussing the funeral and the mass of my mom for tomorrow. I was like if that was offensive to you you can always say that, because now that interaction turned into a whole other thing. she was like I'm making this into a different thing? you are the dramatic one!, I don't care about whatever because you're leaving anyway. I was like that's not what I was saying, + this is so hurtful why would you say something like that. she just gets more and more passive aggressive and I'm just like or you don't care or your level of emotional intelligence can't grasp or understand this . (which is rude I directly realized) the other housemate was just like resume this later because this is not going anywhere. during the house toors when I would speak she would be sighing, looking away. the three of them just create this hostile, uninterested space when I'm around that directly turns off when I'm not there.

for all the days that have followed until now everyone has been distant towards me and they hang out with the 3 of them now. the housemate I was living with the longest doesn't talk to me or look my way at all. she text me to command me to do this or do this, but the only interactions I have with them is when I'm doing something that is bothering them. when I ask something it's a mm or sure. I'm glad I will be moving out because this it's so weird to feel unsafe and unwelcome in your own house. I just keep thinking about what I could have done differently and if I'm the one at faul
