Let me know your thoughts when you google it. My aunt was a registered nurse for many years. At one point in time she worked and shopped and enjoyed her life. From what I understand of MCS it is progressive in that the more exposure you get the worse your symptoms and body degenerates. Thanks for the info on steroids. I am sure there were other reasons for her decision besides just the medication. She also has fur babies, 2 shih-tzu's that keep her company all day. Another thing you might want to think of is where you have been and what you have been exposed to on your worst days. Say for instance your trip to the hospital where your chest was tight and you couldn't breathe properly. What did you do that day that could have lead up to that? I am not that knowledgeable on MCS, but I try to look up and understand as much as I can. I look at it the same way as IBS. That nobody really understands my aunt and what she endures. For many years, everyone (family included) just thought she was a hypochondriac and willed herself to be worse. I can see now though that the problems are real, yes depression may hinder the process of getting better but they are there. Hope you are having an okay day and take care, Bethany
