AITA for getting my(21F) mom(60F) a hospital room upgrade for my comfort?

I (21F) am a uni student and my mother was admitted to the hospital for an infection that caused her to be very ill until she needed assistance out of bed. I love her very much and can’t bear to see her like that so I stayed with her during her stay since my dad had to go to work during the day and need good sleep at night. He visits to bring me food and a change of clothes once a day. My mom has insurance but it covers the very basics and gets her in a shared ward with 3 other patients. Her bed is the farthest from the shared bathroom and she would only tell me she has to go when she can’t hold it in and would leave a trail to the bathroom which I would clean up, clean the bathroom and wash her soiled clothes. I get to rest on a single seating couch but after 2 nights of bad sleep and me having to go through online classes with headaches I asked my dad if we could upgrade my mom to a single room with a lounge that I can sleep horizontally on. It costs a lot more per night and insurance won’t cover the cost so my dad said he will pay no worries.

When we changed my mom was a bit ticked off because now we have to pay more. Dad is paying, not her and he was fine with it. Now, thankfully she’s well and at home. Our relatives were visiting and when I went to make us something to eat I heard her tell them her experience in the hospital and got annoyed that “I” had asked for an upgrade because I was uncomfortable with the basic ward. Basically painting me as this spoilt brat that can’t stand staying in the “poor people” ward. I have a problem with standing up for myself and I just served them food while trying to hold back tears and was so embarrassed.

My judgment is so poor so was I wrong to do that?

Edit: there seems to be a lot of issues about my culture that I did not expect. To clarify, I am Asian. I don’t live in the west. There’s a thing called filial piety here and the healthcare system sucks. The nurses here suck. I am aware of their job scope but I can’t keep running out to call them when they did not respond to the call button. The money thing is really isn’t a big deal as you make it out to be. Trust me, my mom doesn’t care about how much money was spent. She just hates insurance companies and wants them to cover the entirety of the cost but since she changed rooms she’s mainly pissed off that insurance will not cover that.
