I'm learning the subtleties of the differences between being depressed and not depressed.  
1. Perhaps things had more fun in doing them when I wasn't depressed.  For example, if I was trying to cook for 70 people, but had no idea how to do it, the adventure of it brought the task a feeling good.  But the thought of attempting to cook for them when I was more depressed was a dreadful feeling of not wanting to be involved anymore.
2. I ran with the dog today.  Last time we went for a walk, I was walking much slower, and I didn't want to walk more than one lap.
3. I swept and mopped my house today.  Before I would just want to walk past the mess and leave it for a time when I wasn't depressed.
 
Maybe I do feel sad when I'm depressed.  I always said I don't feel sad.  Perhaps the nothingness looks like sadness.  My face is longer.  There's no gumption in anything I do. 
 
Last night was the first time I didn't take any Risperidone.  Perhaps this is the difference.  Perhaps enjoyment has returned.  In 3 days, we will raise the Wellbutrin.
