I have this too.
I frequently stare into space and am semi-conscious that I am doing so. My thoughts are going away from me, I vaguely recognize that I am “thinking,” but they seem far, far away.
I often feel detached from my body and from those around me, as if I were experiencing a dream reality. Everything seems to move smoothly by me, as if the world is quick but I am slow.
I cannot think clearly. I struggle to work and maintain normality. I thought my cortisol was low and that I had Addison’s disease but my morning cortisol came back relatively high.
The only thing that helps me is a little bit of red wine. Somehow I can function as a human for a brief span of time before lapsing back into the void.
