Me too, I have experienced slipping into a state almost describable as denial.  It's not denial tho.  Denial is a deliberate deception.

This is a blanking out of information that just happens naturally, like a mist coming down.  You don't think, you don't retain, you hold onto familiar beliefs.  Above all you don't follow that, um what was that thought again?

It's like putting a bandaid on, it's only a temporary solution.  at some point it wears off again.  and you're back to questioning why am I so uncomfortable, why isn't this working what am I doing wrong...  

I don't think bamboozlement's last forever.  But I see people every day attempting to live with them.  and it can get pretty bad.  and I do quail at the awfulness of it.
