My vision is not really yellow, at least not like a yellow filter or something. I can see all the colors, but the contrast is strange, everything looks 'sickly' especially at night everything looks lid by candlelight. It's a bit like walking from sunlight into a dark room, but also not exactly. Everything looks off, but now like an edited photo.
It resembles more the vision when you are very ill, with a high fever and your brain is not working properly. I remember when I was a child and I had the flue, a high fever and unrelenting and intolerable nausea because of Cyclic Vomiting Syndrome, I had almost no sleep for days because I was throwing up every 3-5 minutes. And that is sort of how my vision looks, but far worse. I can't tolerate low lighting situations, everything seems off, sort of far away, slowed down, like I am on a heavy sedative, but also darker, wrong contrast but not really like what you would get when you would post-process a video with filters or something.
My brain feels ill like it's stuck in constant 'sick mode'. I read that your brain has a 'mode' when you are ill. I think I may have some higher brain inflammation, that sometimes gets worse and I feel even worse. But of course, I can't be sure about that. But I also suspect diffuse brain damage and GABA (too high) NMDAR (too low), Dopamine and Norephedrine involvement.
This is 24/7 every day. It varies between 65% (sedated ill/drugged/drunk) on a sporadic 'good' day, the average is 70-75% (sedated/drunk/drugged), and at worse almost totally unbearable 90-95% drugged/drunk where I can literally do nothing and every second is agony).
