I feel like my friend doesn't like me and I don't know why

Me and my friend have been friends since 2023, we've gone on holiday multiple times and always had fun, but since the start of this year something changed in her ways and I don't know why or how. We went to Disneyland Paris in 2025 together and had an amazing time, no arguments, no bad feelings, nothing out of the ordinary and enjoyed it. We went again this year in 2026 and it wasn't as fun. She didn't care for the shops as I admit they where the same as last year but her energy wasn't good. She didn't care for the rides much either which we loved last year and even the food she only would eat McDonald's which felt pointless. Both days we went we left early, and she complained after that we didn't stay for the fireworks even though she didn't want to stay for long, kept saying her feet hurt, nothing to do, etc. After those 2 days we went to main Paris to go shopping, I went in a total of 1 shop and she complained the whole time, we walked and did some site seeing which she preferred and again ate McDonald's as its all she ate the entire trip. I ended up crying and texting my dad on the night saying how she had stressed me out the whole time and I wanted to be home. After that on the way to the airport we got the wrong train and I had a full on panic attack but luckily we got back fine and home. I broke down to my Dad and said something felt weird and idk why. After that I felt on edge for the friendship and felt a shift in it.

Fast forward multiple months and we've from the UK to Australia together which I was anxious for as throughout those months we kept close but I 100% felt like she was acting different, more snappy, rude, jokey but in a meaner way, and making me feel dumb.

We're now 2 months into Australia and I've been making new friends here because going out with her and trying to make plans is exhausting. I don't even want to explain as I know ill break down or feel shitty but I just don't know how to tell her that she's changed and is making me feel like shit almost daily. If I make a stupid joke she either laughs or rolls her eyes or try's to correct it, if I ask what to do she always shrugs, eating and plans are impossible its always a shrug and I have to pick with a 'I don't know!?' and a stare, when we do go out she doesn't want to shop, so then I go in stores and she's bored with arms crossed.

I just feel like we are so so so opposite that It's making me so insecure. I grew up being bullied, picked on, made the joke, not taken seriously and never had proper friends so on one hand I'm used to this on the other it really hurts as I cant just stop being her friend or slowly see her less as we live together, we don't have jobs yet and she isn't making an effort to go out, make plans or meet new people here. I think that because I have friends and putting myself out there I'm slowly giving us distance which I do enjoy, I just wish she would do the same so then we have our own friends and places to go and maybe she will relax and come back to me and say 'im sorry if I was snappy' and ill say you where and its okay its a new place and your picky etc

I feel stupid posting this but im so lost on wtf to do. I'm considering saying something like a message, letter, or in person one day before I go out or if we are out having a chill time but im worried she will deny it or ignore it but I think she will understand and apologise but im just scared she will blame me or say im dumb im rude or whatever idk
