Wow, what happened?

Yesterday, I was feeling refreshed – almost to the point where I thought I must be getting better.  But now, oh my, what a contrast!  I didn’t feel I was pushing myself yesterday – did a couple loads of laundry and started sorting through my Dad’s stuff even though I didn’t get far with that.  I seem unable to face that yet. In the afternoon, we dressed up and went to a wedding.  The church was cool as was the reception, so I didn’t get overheated or anything.  We had a nice time.  I started to feel a little sluggish and breathless just as the wedding dance started, so we came home.  Still felt okay when I went to bed.
But this morning!  I slept two hours later than usual and awoke with a puffy face and feeling like my arms and legs were made of lead. Getting dressed was a chore and left me breathless with my head pounding.  My stomach felt a little queasy at first, but the omelets D made smelled good and I devoured mine.  I tried to sit on the deck swing since there was a cool breeze, but I just wasn’t comfortable.  Cudi wanted to play fetch, but one throw was all I had in me.  I came in and tried to finish the book I had started while camping, but I just kept reading the same paragraph over and over, failing to comprehend it.  I fell asleep watching TV so went to bed and slept another THREE HOURS.  I feel a little better now but my limbs are still heavy and my brain is dull.
