Very sudden, extreme food aversion

I’ve never been a super picky eater, except for a small number of things I know I don’t like. Regularly, I’d eat something for lunch and dinner with a snack or two throughout the day. Over the past 2-3 weeks, I’ve developed a very sudden aversion to almost every food. I’m currently eating maybe a snack a day, which I know is not good.

Whenever I choose what to eat, I’ve always had to imagine the taste and texture in my mouth before I decide what I want. This seems “normal” to me. However, lately everything feels wrong. I usually grab a fig bar on my way out of the house in the morning, but one day it just felt like mush in my mouth and I felt like I needed to throw up, it just disgusted me. After I realized most of the foods I like that are soft did that, I started looking for crunchy things. But after I chew, that also turns to mush. I found a very crunchy granola bar, took one bite, and after one or two chews it wasn’t even “mushy,” just felt so BAD in my mouth that I had to get it out.

I’m still hungry, is the issue. I’m very hungry and nothing feels right, so I can’t eat it. My partner is worried about my lack of nutrition and actual food intake, and I am too. Has anyone else experienced this? Does it go away by itself and I just have to wait it out, or am I just living like this now? Any help would be very appreciated :) thank you
