Maybe that's it. The thing is sometimes his eyes seem normal and sometimes they seem wild - that shiny stare. Last night he was going back and forth. One moment he was stressed and wild-eyed, then the cat walked through the room. He picked it up and petted it and relaxed. His eyes went back to normal.

It's more than his eyes. It's the way he walks and stands. Huge tension. And it seems like even his breathing changes but that's probably my imagination. He has complained of breathing problems - unable to take a deep breath. It's hard to know if psychological tension is feeding into physical tension. Or vice versa. Or a cycle?
