I am saddened by your story and find myself in a similar situation at work but I have a lot of support from most of my co-workers and HR has committed to help. My family members are not ones that bath in fragrance but some ware deodorants that they are unaware that they cause problems. I don't want to be a nuisance and will avoid them. As my condition worsens I will have to put myself first.
You have to take care of you, because trust me no one else will. Just remember the more you are exposed the worse you become. I now am finding that hugging people is very problematic. I am contemplating not doing it anymore. People may be offended but I am sorry but my health comes first.
