Of black moods...........

I have always been a moody character. But now I get these vicious black moods almost daily .And to top it all, I have to constantly hide it between smiles, jokes and laughter.I have to keep a constant check on myself to ensure that it is a proper act and not over acting as it happens sometimes. Yes , as a friend said I am an actor par excellence when it comes to hiding my feelings especially of sorrow, hurt and anger but I don't know how long these charades will last..............
