A mood swing is an extreme or rapid change in mood. Such mood swings can play a positive part in promoting problem solving and in producing flexible forward planning.
However when these changes start to become controlling, mood swings can start to adversely affect the way someone functions.

Where no storms come,
Where the green swell is in the havens dumb,
And out of the swing of the sea.”
