No, not stupid. Sad and tired, perhaps, but not stupid.

Sue Chance, M.D., wrote of Winston Churchill, "'Black Dog' was Churchill's name for his depression, and as is true with all metaphors, it speaks volumes. The nickname implies both familiarity and an attempt at mastery, because while that dog may sink his fangs into one's person every now and then, he's still, after all, only a dog, and he can be cajoled sometimes and locked up other times."

Peace be with you. This too shall pass.
