I have to admit it's hard to think of a "good" day as something other than "doing lots of things". Having depression means I've had to adjust that way of thinking, & while I do love having a productive day, these days it's a measure of how depression is impacting me, more than my worth as a human being.
& sometimes (not so often these days), a "good" day means I woke up alive the next morning.
Time for me to pack it in today & go have dinner, do a couple of chores, & relax for the evening. Later gators!
