When my anxiety is acting up, I find I can't concentrate, and can't even do the most simple and mindless of tasks. This afternoon I didn't so much as want to play videogames. I just wanted to lay there, and not even to sleep. I still don't want to sleep, or do anything, and it's a wonder I'm even posting this. Can't you relate? Do you sometimes feel like a complete zombie when you start to feel anxious?
