I sometimes have hallucinations that I smell very bad, despite the fact I used too much soap to make myself smell good, and I used too much deodorant to make myself smell good and I still have those hallucinations that I smell very bad.
I don’t know how to help with that. But if you shower regularly and use deodorant you’re most likely not smelling. Just keep telling yourself that you are clean and therefore not really smelling. I know it’s easier said than done though.
