'Depressed' in the Bible

Then in the month of Nisan, in the twentieth year of King Artaxerxes, when wine was brought to me, I took the wine and gave it to the king. Previously I had not been depressed in the king's presence.

So the king said to me, "Why do you appear to be depressed when you aren't sick? What can this be other than sadness of heart?" This made me very fearful.
