Black Dog Day

What started out as a good day has turned into a "Black Dog Day". I think Churchill's phrase captures the essence of such days perfectly. They are days when you feel down, regardless of what happens during the day. If the glass was once half full a minute ago, suddenly it looks very empty. Something in my heart tells me there must be some root cause for such wild shifts. If I find it, surely that will help me control it.

Despite my belief that there must be some root trigger for Black Dog Days I have yet to find the cause of today's one.
