Thanks David,
Didn't mean to sound so blue.  I alternate between happy, singing, feeling great and acting silly to having a couple of down days.  The down days are when I focus too much on cancer.  I start getting scared of my next PET (Jan 16), worried about recurrance and all the other stuff that goes with cancer.  
Lately after each doctors appointment, I start shaking uncontrollably for about 20 minutes.  It's the wierdest thing -teeth chattering & shaking.  I feel fine at the appointments-calm, but as soon as I walk out it starts.  It makes me laugh.
