Monster of Emotions

Sometimes when an emotion is trying to grab hold of you all you can say it "what's going on"... and then it has you.

I walk... I run... I laugh... I cry... What type of emotional being am I? Just like the seasons, Emotions change. Some are strange; And some sound the same. Ebbing and flowing, like a gentle tide; Tell me what type of being am I? You must wonder, and so do I... What type of emotional creature am I?
