Paranoia is an old friend of mine, can't smell myself at all and 'rely' on others reactions so you find you are constantly second guessing people as not many will come and say 'you stink', I've just learned to try and focus on other things and realise that family and friends are what counts and also that it's not your fault you smell..we're probably the most hygenically aware people on the planet.
I am diagnosed but understand your fear about a -ve test, however you need to overcome this if you want to try the management techniques that may help you (ie, antibitoics, diet advice etc.)
you're amongst friends here, keep your chin up...
