AITAH for not going on a planned outing because plans changed and i couldn’t afford it on my own.

So my friends wanted to go to a city on a night out that one of my friends live in. I was going to stay round hers so i wouldn’t have to pay for a hotel or anything like that. Originally there was 4 of us getting an uber there and back so it’d be quite cheap between us. Then two of them (they are a couple) decided to get a hotel instead and got a train (which i could not do as i had a shift that day). Then the other friends dad said he didn’t want her going to that city. At this point i had just done my last shift at work the day of and i didn’t have enough money to go out because i have to pay for university items. I said i cant go now because i cant afford a £50 uber there and back as that was literally all the money i had at the time. The friend whos dad had just said she couldnt go said shed pay for my uber there. I said i dont want her to because its way to much money. But the others said to let her be nice, so i agreed. I then said id have to ask my dad to pick me up. I kept asking my dad and kept updating them he kept saying maybe. Then it got to the day i messaged my friend who’s house i was going to that morning saying i don’t think i am going. Later i had finished work at around 5:50 pm and asked he said he didnt want to. And the uber was £57. So i texted them and said i couldn’t go it was too expensive and i have to pay for my university stuff. So then i got called disrespectful and was told i should of bought my stuff sooner ( i work 1 day a week and pay for my own things most of the time apart from food) i said i was sorry and what do you expect me to do i cant fly home nor can i pull money out my backside. I admit that was abit much but i had the couple spamming me saying i was taking the piss and all this even tho i cant just get up and go so i was stressing out because they were so angry. My friends whos house i was going to btw said it was completely fine. I went out that night in my town as i didnt need to pay for travel or drinks because i had friends paying. Of which they started going oh i thought u had no money and messaging my friend saying why am i out. I want to know AITAH for not physically being able to afford to get to that city and back.
