So I'm on Day 12 and I have the most awful brain fog. I feel like I'm walking around like a zombie. I've tried logging on to work but I just can't concentrate on anything. It feels like my head is spinning and Im totally spaced out. I'm really scared about long covid and that this feeling will never go, and its making me panic. For those who have had this, but not turned into long covid, how long did it last before it started to get better? Can it get better?
