Replying to Noseblind issues

I can smell stuff but not very good. When someone rips ass or something smells bad its nice but other times it sucks. Like I just caught a whiff of my jacket and it lowkey smells like shit. So now I’m over thinking “fuck. I wore this yesterday when I went out and all day today at school” I wonder if people next to me are like damn this fool smells like ass. And I can’t really tell if I do or not. Anyone else have bad sense of smell
