advice needed

so on new years eve me and 5 of my friends are having a sleepover/party to celebrate new years the party is being held at my friend jacobs house

ive been to jacobs once before and while i was there my anxiety was really high and i ended up going home after an hour because it made me feel nauseous

i worried about going because i dont want to miss out because my anxiety is bad and ive tried everything like drinking water and doing breathing exercises and even been on a temporary medication for unexplained nausea

i was wondering if anyone had any tips to help increase my chance of being able to stay there
