Yes, every day. I work in a very busy Whole Foods. The loud music and flourescent lights, combined with work stress and having to interact with so many people in a day. It's very difficult, and I take many breaks and the bulk of my anxiety meds at work.
I usually go sit on the steps in the alley at the side of the building where it's quiet. I stand against the wall and bounce off it for a while. Or go sit in the nearby burger king, which being next to a whole foods is always dead, quiet, and relaxing.
I risk getting in trouble with the number of breaks I take in a shift. And even that sometimes doesn't keep me from complete meltdown.
I'd much rather do something working from home. Or to be a librarian, that has always been my humble dream. Quiet, and surrounded by books, all day, and getting paid for it... Heaven.
