I think you have a problem with anxiety. Even if you smell you can't smell that bad if you don't get the questions about an odor around you. The thing with anxiety like this is that you LOOK FOR REACTIONS. You take any thing that happens around you as a reaction because YOU ALREADY THINK YOU SMELL!!! So the littlest thing will make you think you smell. You think about the "reactions" more than the non reactions or the things that happen that show you you don't smell.
