As far as I can see, what you're describing is not drama queens but emotionally challenged people. If we start to use the word drama queen about the emotionally challenged (as if we're not all emotionally challenged to some extent), then what word do we use for people who knowingly uses their emotions and the acceleration of these to control and manipulate situations and people around them? Because as far as I know, that was the meaning of the word drama queen until you came around with you article.
