Difficulty concentrating feels like a pressure in my forehead that builds the more I fight it. Thats when it's strong, other times, I just find myself doing or thinking about something else.

Difficulty getting to work more often takes the second unconscious form. I don't dwell on it, I just find myself not doing the work. However, sometimes it feels like an empty, hollow chest area and the more I think about the work, the more hollow it feels. However, the more I don't do the work, the more weak/hollow my arms feel.

I find it interesting how my kinisthetic intuitions match up with your visual intuitions.
