Anxiety comes and goes, is big sometimes and small sometimes. I'm trying to learn how to identify where my anxiety is in a given moment, and my therapist recently asked "what physical sensations are clues?"

I get this feeling of what I can only describe as 'fog'. Like my brain is underwater and needs to work extra hard to make connections. Like my eyes need to work extra hard to really see things. Like I have to remember sometimes "these surroundings I'm seeing right now, I'm here too. I'm not just looking at things- I'm *here*". 

I don't mean in a literal sense; things don't actually look fogged over, but that's the best way I can describe the feeling so far. I'm having a really hard time finding a more articulate/accurate way to describe this sensation, so I thought I'd see if anyone else experiences something similar and can help put words to it?
