I don’t know why but when I see bright fluorescent white lights it triggers anxiety attacks and derealization. I went into a store while I was on vacation, everything was white, the floor was super shiny and they had very bright white lights, I had to run out of there because I felt so scared and I felt like I was dreaming. I don’t even like going to therapy because they have fluorescent lights and the walls are white which causes me to panic sometimes, especially when talking about topics I’m sensitive to.
