am i wrong to be upset? was i ungrateful?

my mom and i went over to my aunts today to visit my nana (she won’t take her over for christmas or anything when we host cuz she wants us to make an effort). for christmas she said she’ll pay for us 5 (not her or my nana but the rest of my fam😂) to go paintballing which is a great idea and sounds fun. we went over and she started talking to my mom about it, and my mom said she’ll only have to pay for two (my dad and brother) cuz her my sister and I don’t want to do it because when the guys go they wear many layers of sweats and protection and still come home with welts from the paintballs and it’s painful. i’m sure it’s very fun but i dont trust other ppl there and dont want to have welts.

my mom said it nicely, and my aunt turned to me and began to yell at me. she was calling me an ungrateful bitch, and said “would it kill you to have fun for a couple of hours for christ sakes?! you don’t have a choice they have fucking protection for you” and continued to yell. i remained silent and my mom tried to calmly explain but she wouldn’t listen (my aunt always yelled and my mom learned yelling back makes it worse)

obviously i was upset, and the rest of the time i was there she would find the tiniest thing i was doing and would scream at me nonstop (i brought a latte with a lid into her living room where my nana was and she thinks i’m 5 and not 17 so she kept screaming “don’t spill that on my ducking carpet” and stuff so i just left it in the kitchen after a few yells. i literally was holding it for warmth not drinking. i understand she doesn’t want me to spill so she should’ve just told me not to take it in)

anyways i spent the entire hour there turned away from her and crying so she wouldn’t see as she yelled at my mom for whatever popped into her head. i just want to know, am i being ungrateful for the gift/ overreacting for still wanting to cry just thinking about the visit?

also it’s not like we want her to get us something else, we don’t want anything from her. this doesnt matter but small detail: whenever we get her a birthday or christmas present, no matter what it is (hd tv she wanted or something else) she returns it.
