"One of the most frustrating aspects of multiple chemical sensitivity (MCS) is the lack of understanding and acceptance of the condition by those around the person with MCS. Often, people with MCS are subjected to well-meaning, but ignorant, comments that can be deligitimizing and hurtful. Comments may take the form of unwanted advice, insults, and simple disbelief.
Learning how to respond to these comments, educate others, halt abusive insults, and diffuse unwanted advice can be the difference between healthy adjustment and despair. There are several response approaches which each serve a different purpose. The approach selected depends largely on whether one wants to diffuse a situation, end the conversation, or engage in educating someone about MCS."
