Nightmares Followed by Apathy

Two nights ago I had horrible nightmares, complete with nausea and hand washing.  It was an exhausting night.  What followed was even less fun:  Total Apathy.  My wife would ask me a question and I would say 'whatever'.  I didn't care about anything, couldn't.  I was completely empty of any emotion.  For a bit, not even my beautiful daughter could evoke an emotional response.
Caley was the one who eventually broke through.  She kept on wanting Daddy Cuddles and she looked so miserable that I wasn't paying attention to her that I finally broke down and put her on my lap.  We cuddled and I started feeling a sense of well-being again.  Her love is so unconditional.  I am still feeling emotionally distant today, but I'm getting there.  I have today off and will sit down and reflect on this past weekend.  Hopefully, that helps.
