Feeling better in different places?

Hi, im not oficially diagnosed, but the symptoms are pretty clear, and i pretty much tested and ruled out every other disease. So here my question: why am i feeling better at work? Its not like at work im cured, but for example at home i also sleep worse than in hotels or at my girlfriends home.

Could there be invisible mold in our House?
We even had our ventilation system cleaned and checked for mold.
Its fairly new and we never had any visible problems.
Could it be wifi? But there is also wifi at work!
Could it be chemicals or laundry detergent that my mother uses?
What could be the thing i react to ???
Did anyone have similar experiences?
