Stress is tricky. I got the smell of a particular perfume in my nose this past week and I couldn’t get it to go away. I went for a couple of days thinking that I could “think” my way out of it. That didn’t work. I returned to a complete retraining process and it went away without me thinking about it.
There are times now where I still think that I can think my way out of chemical sensitivity. It is pretty rare these days to have reactions, but I still don’t like certain smells. A quick retraining is very helpful in those situations. And, it is entirely okay to still not like certain smells. It is all about balance.
I do think that stress is a factor. It may mostly be a factor in reverting to the belief that you can think your way out of the situation.
The retraining involves very concrete steps to use. You are changing the way your brain responds to stimuli. But, you are not thinking your way out.
