I've had derealization in connection with my anxiety for probably the past 8 months. I feel like I'm in a dream like state, I think people often call it brain fog? It's a lot more manageable now, but it does make my anxiety worse as I just don't feel there. My body is there, but it feels as though my mind isn't. I suppose it could be the freeze response, but I get it all day, every day. Even in doors at home, whilst watching TV. I can't help noticing it, though when I don't pay attention to it, I don't notice it. Anyone else had this? And has anything helped with it?
