How has your odor impacted your friends/family?

I ask this because as hard as it is on us, it can't be easy on the people that love us, however, few they may be. I was at a friends house last month. We had a nice little bbq outside and had a great time relaxing outside gazing at people driving by. Then I noticed that people were driving by and holding their noses. I sniffed hard trying to detect any odor and I couldn't outside of the BBQ scent. My friend seemed to notice too but didn't say anything. We were in an area of the yard where we couldn't be seen from the road. The only thing visible from the road was my friends car, the grill, and the house. I don't know what the scent was or could have been or if they saw me and automatically reacted. I felt so bad for my friend. I hate that my odor could possibly have a negative social impact on them. I've stayed away since then because of this. It's the same way at work. I notice people pass by and hold there nose and it makes me feel terrible. Especially for my coworkers who don't at all deserve to be stigmatized and treated like I am, which i have witnessed at times. I don't know what to do to change any of these situations. I just avoid my friends now and keep my head down at work. Anybody else have a similar experience?
