I wonder the same thing too. I've been battling this for 7 yrs now. Since that time I have been diagnosed with schizo affective disorder and psychosis. I hear voices that make fun of my smell. I smell things that no one else smells. Usually its a bad smell like a fart or poo. But I have also had reactions. I dont get them often. I've been going out for a yr now and have had like 10 reactions. People dont usually cough or sneeze around me but they do look at me sometimes with this unapproving look.
No one has ever told me I smell. I've actually had a couple of people say I smell good, or my hair smells good. I know I have bad breath but I'm up and down about believing I smell.
I was in the hospital from Feb to March and I barely took a bath while I was there. I mean I would go like 8 days without taking a bath and I had someone walk in one day and say whats that smell... That was about it. I also had one girl play in my hair and tell me it smells good but I hadnt washed it in like a month. People were hugging me and hanging out with me but I just dont know because there are reactions to the contrary.
After I got out the hospital I went on vacation with my mom and neice. We went to a childrens indoor water park for 3 days. No one said a thing to me while I was there and I was out and around people the whole time. They would stand closer than I want in lines and stuff. There was even a kid around 10 that hung around me talking to me the whole time I was at the arcade and I was wearing perfume. I was eating horribly around that time too seafood, eggs every day, tuna fish. I dont know what to believe because I get both reactions and non reactions. I know I'm crazy but I just dont believe its all in my head no matter what people say.
