Please help! any advice?

I have been suffering with this problem for a few years now. I've been told I smell musty, or at times like feces. The smell seems to change from time to time and some days I have no odor. Family and friends always tell me they can't smell anything. but i get nasty comments/reactions so i know I'm not crazy. I've been to doctors and they have given me no real answers other than giving me drugs for Depression and telling me to drink more water and other stuff that hasn't worked. they treat me like i'm crazy because they say they can't smell me. Although i realize i do not have an odor all the time. anyone have any advice. I'm at the point I want to quit my job and move home.
