My coworker has a terrible breath it makes me sick

Bro istg I don't know what to do rn. Bro, this coworker's breath is so fucking rancid ma I can't even look at her. I'm not exaggerating when I say that it smells like she ate a bowl full of tonsil stones for breakfast. Genuinely, I have horrible nausea rn (I did eat breakfast). And it's not only her breath. It's like she has an issue with body odor in general. After a couple hours, I smell her breath, her pits, her crotch... We work like shoulder to shoulder man. We do NOT have trust in eachother so it's not like I can approach this with her. I'm honestly up for switching seats man.

I understand that not everyone has a car or can afford taking an Uber to work and rely on public transportation. But I also believe that if you are aware that you have a body smell issue, maybe take some extra measures like bringing an extra shirt, deodorant, a toothbrush or just some gum.

I always bring a pack of gum with me so, to be more subtle, I offer gum to everyone around me and THEN her. But when she declines bro... I wanna cry. I feel like I have become paranoid with my own breath. I don't wanna cause other people what this girl does to me. I brush my teeth constantly, wash my retainers and always carrying gum around. Kinda lost rn.
