Sorry, Waves,
I wish you could move yourself to a new situation in time or place.
I can understand how feeling suffocated would make someone feel "off." I think when we have our own "space" we feel protected.
(Tdoc bugs me to find a place in my home that is all mine. Apparently, she imagines that I will use this space as a quiet space --- not for computer or tv or reading -- and certainly not cluttered.)
If you could stand to go outside with heavy sunglasses you could still benefit from Vit D. I noticed that after being vigilant abut taking between 2,000 and 4,000 IU daily for about 4 weeks along with a handful of things close to what you mention I did feel one degree better last fall when I felt awful. The vits and sups took me out of the not awful range.
Hugs.
M.
