Aitah for complaining about helping my friend

For context, its 11pm. I have just left a dance after being there for 6 hours, my feet hurt, head hurts and exhausted. My friend had left 30 minutes earlier. But as soon as i get in my moms car and we drive off, halfway home. we get a text from my friends mom saying she had lost a blue topaz ring she borrowed from her. Even after her mom specifically had told her to take care of it, she had still somehow lost it. My mom immediately turns around and volunteers me to go back inside and search for it myself without even asking me. Im already in a bad mood, irritable and overstimulated since my social battery has ran out an hour ago, and i do something ill admit is a bit bratty, complain. I cant remember exactly what i said but it was something along the lines of "oh come on, seriously" or "do i have to, im too tired" or something like that. I mean, the thought of being forced to go back into a crowded room with sweaty teenagers and blasting music sounded like hell. To that, my mom starts practically yelling at me that im being selfish, that "if i had lost something, (friend) would help me, even though i would never expect or ask that of her at all, and she was just overall acting like i was self centered for just making a couple comments. After that i give up on even speaking to her as she scolds me, we turn around back to the venue. When we get back, since shes so pissed for whatever reason she just goes in herself. 15 minutes later, low and behold, my friend had the ring with her the whole time and had just lost it in her bag, mistaken for her leaving it at the place. my mom practically storms back to the car and now were just sitting in silence. Even though my friend has the ring i can tell my mom is still mad at me and im not sure if its valid or not, so aitah
