Has anyone else ever had an entire person become a trigger?

I live on campus and I have a roommate. Just imagine an en-suite with two beds, so there’s absolutely no privacy. My roommate does everything i hate. she eats loud, she’s a mouth breather, and she moans in her sleep. On top of that she eats constantly and throughout the night aswell, so I constantly have to keep my earphones on to avoid being triggered, even when im trying to sleep. Now whenever I see her i get instantly annoyed. and whenever she does things that don’t normally trigger me, like laughing or talking I get angry.

Earlier today I saw her walking back to our building, and i got triggered just by looking at her. I had to turn the other way. Has this happened to anyone else?
