It gets better if I unfocus, meditate, listen to music, or do various stress-relieving things. It gets worse if I watch TV. TV is interesting, because it's like an addictive compound. If I'm in this state, I crave it, but TV makes the mental state worse. You want to even watch mindless junk, in this state, channel surf, or have it playing in the background. But it makes the attention deficit worse, and puts you into a nasty mood. I call that an addiction. Stressed? Kill the TV.
I have a feeling that it's caused by information overload. The brain is trying to process too much, and is starting to do things in shorthand. But some basic process thinks that it's just that it needs more information to be able to sort things properly. Which isn't the case, but it's spoofing the brain into thinking so. Hence the craving for things like TV. Fortunately, I seem to have a security valve, that will put my brain into shutdown/veg mode, if I really, really need it. But this is getting worrisome. I need to just get away and stare at trees for a while.
