Has anyone been diagnosed with a mental disorder when they talked to the doctor about their bo?

So whenever I try to talk to a doctor about my Body Odor not only do they say I dont smell but they tell me I'm delusional. They say that what I believe is not true and that no matter what people tell me I won't believe the truth. Have any of you ever been diagnosed with a mental condition like delusional disorder schitsophrenia psychosis etc..... by doctors when you tried to talk about your Body Odor ??? See I dont know who to believe. Should I believe the doctors and my family or should I believe myself.
