Emetephobia 😰😰😰

(For any of you who didn't know, emetephobia is the extreme fear of throwing up haha)
Anyway I'm staying at my boyfriend's house for the night (in the guest room, which is next to the bathroom) and I was asleep but woke up to the sounds of my boyfriends brother puking and I'm having the biggest panic attack ever rn and now I feel like I'm going to throw up. I'm shaking and sweating, like absolutely terrified and I have no idea what to do. Any advice??? :( I know it's dumb but it's a serious phobia I have.
