I believe mine is all in my head but it's a psychiatric condition from schizophrenia. It's called somatic delusions. I'm on medication and they worked before I stopped taking them for 2 weeks. It took 7 months but the thought totally went away and I was free. I went everywhere and did everything. I went to a program for peole with mental disorders and had a great time. They were all so nice to me. We had to drive home in this small van and I wasn't worried. No one reacted and the windows were rolled up. I also went in the mental hospital and didn't take a bath for like a week at a time and people were sitting and talking with me with no reactions. They even hugged me. One person resting his head on my chest for a few minutes.
I've had many experiences like that that show that I don't smell but when I'm not on medication I worry about it. I seclude myself and don't believe anyone. Everything makes me think I smell. If someone looks at me it's because I smell. If they make a sound it's because I smell. It doesn't matter that the person behind me in line stood just inches away and didn't react. All that matters is the bad.
I've been out over 1000 times and have had at the most 15 reactions but that doesn't matter. And a reaction for me is not a reaction for others. Like if I didn't already believe I smell they would mean nothing but since I think I smell they mean alot.
