Not sure where to post this

I’m posting this here because of health. My anxiety has been awful awful lately I’m about 3 months pp. I was exposed to someone at my work being close contact with covid last Wednesday. I was tested Sunday and it was negative. Well my question is can anxiety and stress etc make you feel like you have impaired taste?! This started two days ago I can taste but maybe I’m thinking to hard? I feel absolutely crazy and I can smell stuff just fine. I just know it’s a sign of covid so maybe I’m making myself have this?
