I'm not a doctor, but this sounds like Mikrophobia. I do recognize you're describing your feelings as a kind of revulsion, not fear proper, but still that'd the best pattern match I got.

I suggest you talk to a psychiatrist or psychotherapist about it, because if it is that, your issue is very solvable. Phobias are one of the easiest-to-treat psychological issues; desensitization and cognitive-behavioral therapy work quite well.
