Am I imagining the smell?

Hey,

I often imagine that I have an unpleasant body odor or that, for example, my jacket smells, and I also notice this smell.

Since I've already asked several trustworthy people whether I'm just imagining it or whether the smell is really there, and they've denied it every time, I suspect it's something psychological.

There's basically nothing I can do about it. I shower every day and constantly feel the urge to wash my clothes so they don't smell anymore, even though they don't.

Somehow I'm aware of this too, otherwise I wouldn't write it like this here, but as soon as I go somewhere I get the feeling that things have changed and I'm unkempt and then I get worked up about it.

Is there a term for this, or how can it be explained? Any idea? It's pretty special, somehow, but I suffer from it because it makes me feel so uncomfortable, and I'm kind of lying to myself about it.
